Bug Report

Current Behavior:

I am injecting the StateService in a component of a custom angular library I am building. As soon as I do that though, the following happens:

R3InjectorError(AppModule)[StateService -> StateService -> StateService]: 
  NullInjectorError: No provider for StateService!

and the whole app does not work.

Expected Behavior:

No error, being able to use the Service and not crashing the whole application.
