Run Angular component tests only after app initializers have completed.

[samuelfernandez]

What would you like?

Run Cypress tests only after app initializers have completed. Or at least hook into that process and run a forced change detection after completing.

Why is this needed?

Angular component tests might rely on app initializers. Those don't cause the zone to be unstable, so tests are executed before they complete. This is known to Angular tests: angular/angular#24218

However in Cypress component tests there is no workaround to make it wait.
