Current behavior

I need to mock MatIconModule and can't

Expected behavior

I'd like to be able to do the following:

TestBed.configureTestingModule({
  // ...
})
.overrideModule(MatIconModule, {
  // ...
})

But with spectator.

What is the motivation / use case for changing the behavior?

Have all the native capabilities of TestBed and being able to override a module.
