This commit updates the necessary config files to run the angular.io and
docs tooling unit tests in random order (and fixes the tests that were
failing due to their dependence on the previous ordered execution).
Besides being a good idea anyway, running tests in random order is the
new [default behavior in jasmine@3.0.0][1], so this commit is in
preparation of upgrading jasmine to the latest version.

This is to tidy up the `author-packagse`, which currently duplicates a
lot of the configuration in the main packages. We need to
DRY this up so that we don't fall foul of a change in one being missed in
the other.
