Feature Request: inject a directive with providers in MockRender

[satanTime]

Describe the feature or problem you'd like to solve

To test @Self decorators, we need to inject providers via directive.

The code below should work.

@Component({
  selector: 'target',
  template: `{{ service.name }}`,
})
class TargetComponent {
  constructor(@Self() public service: TargetService) {}
}

Proposed solution

MockRender injects a directive with providers if a class has been passed into MockRender.
