Patrice Chalin 64bce18ea7 e2e(dependency-injection): fix for Dart and simplification for TS
Fixes #2493

No need to dual boot `AppComponent` and `ProvidersComponent` only to
ensure that we could demo optional injection; instead just inject null
for the `@Optional` constructor parameter type.

No prose is affected by these changes.
