Current behavior

1. Implement NgxsOnInit and NgxsAfterBootstrap in a state that is imported with root. In our case the state was AuthState:

 NgxsModule.forRoot(
      [
        AuthState,
        // follwed by three other states
      ],
      {
        developmentMode: !environment.production,
      }
    ),
// importing other plugins
// importing module with a NgxsModule.forFeature

1. Load the app

2. Neither life-cycle events are triggered.

Expected behavior

Expecting life-cycle events to be triggered when loading the app at the specified timings described in the documentation.

This is still working in versions prior to 3.4.0 such as 3.3.4.

Minimal reproduction of the problem with instructions

Was unable to reproduce in a minimal reproduction. So assuming it must be some edge-case to do with import order of NGXS modules similar to other issues: #539 and #375. The difference with this bug is that the life-cycle is called in a state initialized by forRoot.

Here is a more advanced version of the minimal demo that still emits life-cycle events: https://stackblitz.com/edit/ngxs-simple-k8i8y6

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

Want to use life-cycle hooks to set authentication state.
