@ngrx/component Implement tests work for Ivy, ViewEngine, NgZone, NgNoopZone, zone free environment

@ngrx/component Make tests work for Ivy, ViewEngine, NgZone, NgNoopZone, no zone environment

Minimal reproduction of the bug/regression with instructions:

We neep proper unit tests to ensure the cone works in:

• Ivy in:
  • ZoneFull environment where Angulars zone service is of type NgZone
  • ZoneLess environment where Angulars zone service is of type NgNoopZone
  • ZoneFree environment where Angulars ApplicationRoot is not present (https://github.com/LayZeeDK/ngx-ivy-minimal-elements-without-platform-and-ngzone)
• ViewEngine in:
  • ZoneFull environment where Angulars zone service is of type NgZone
  • ZoneLess environment where Angulars zone service is of type NgNoopZone

See current state for e.g. the push pipe here:
https://github.com/ngrx/platform/blob/master/modules/component/spec/push/push.pipe.spec.ts#L226

Expected behavior:

All tests are implemented and pass.
