Ngrx Reducer AOT testing

Reproduces the issue where reducer state can't be initialised when the reducers are specified on StoreModule.forRoot using spread operator.

// app.module.ts
StoreModule.forRoot(fromRoot.reducers), <-- properly initialised
StoreModule.forRoot({ ...fromRoot.reducers }), <-- null state
StoreModule.forRoot(Object.assign({}, fromRoot.reducers)), <-- null state

Run AOT with:

ng serve --aot

Observe the following error on the browser console:
