Importing ServiceWorkerModule.register() will schedule registration of
the Service Worker inside an APP_INITIALIZER. Previously, the Promise
returned by navigator.serviceWorker.register() was returned from the
initializer function. This has the unwanted side effect of blocking
initialization until the SW is registered. Even worse, if the SW script
fails to load, this can cause the app initialization to fail.
The solution is to not return the registration promise from the
initializer function, essentially decoupling registration from the rest
of the initialization flow.
This change is not unit testable as there are no mocks/adapters yet for
navigator.serviceWorker. A future integration test should cover this case
with better fidelity.

Currently, the SwUpdate service doesn't receive messages from the SW.
This is because it attempts to subscribe to the 'message' event on
ServiceWorkerRegistration, when really messages are emitted by the
ServiceWorkerContainer.
This change moves to listening on ServiceWorkerContainer and changes
the mocks to reflect the way the browser actually works.

The error collector changes behavior of the metadata resolver
in ways that haven't been fully hardened. This changes limits
its use to the lazy route detection and the language service.

This change is needed to prevent users’ builds from breaking.
If a user sets `fullTemlateTypeCheck` to true, we will
continue to check the templates even when `skipTemplateCodegen` is true
as well.

There is no difference in runtime (yet) between versioned and unversioned
files. Theoretically, the SW does not have to cache-bust versioned files,
but the SW doesn't cache bust files on the first request anyway, so in the
common case it doesn't matter. If the hash doesn't match, the SW will cache
bust the file to be sure, which is technically unnecessary, but since the
file itself is versioned, the likelihood of this happening is rare.
This fixes a critical bug where versioned files were erroneously not included
in the hashTable in the generated manifest. This could lead to applications
not updating if only versioned files changed in between versions.

The GaService and the E2E specs were unnecessarily complicated and had
arbitrary async timeouts to ensure that the interplay between the GA
library code and the rest of the app worked correctly. This resulted
in potential flaky tests if the timeouts were not adequate; this was
experienced when Travis upgraded to Chrome 62.
The new approach is to block loading of the Analytics library altogether
if there is a `__e2e__` flag set in the `SessionStorage` of the browser.
It doesn't appear to be enough just to set the flag directly on the
window. I think this is because the window gets cleaned when navigation
occurs (but I am not certain).
The downside of this is that we had to add a small piece of extra logic
to the GA snippet in index.html; and we also had to switch from using
`<script async ...>` to a programmatic approach to loading the GA library
which prevents the browser from eagerly fetching the library. This may
be mitigated by adding it to the HTTP/2 push configuration of the Firebase
hosting.

When Cache.put() is called with a Response, it consumes the response. If
the Response is used for any other purpose (such as satisfying the
original FetchEvent) it must be cloned first.
A bug exists in the mocks used for SW tests, where this condition is not
validated. The bodies of MockResponses can be utilized repeatedly without
erroring in the same way that a real browser would. This bug is fixed by
this commit, which causes tests for the freshness strategy of data caching
to start failing.
The cause of this failure is a second bug in the data caching code, where
the Response is not cloned prior to being passed to Cache.put(). This is
also fixed.
