Subject: [PATCH] test: use eager change detection in fake-async test component

The `AppComponent` template used within the `fake-async_spec.ts` files
is updated to use `ChangeDetectionStrategy.Eager`. This ensures that
change detection is triggered immediately as expected for these
specific behavior tests.
