generate ROOT_EFFECTS_INIT through createAction

[maxisam]

Currently ROOT_EFFECTS_INIT is defined from

platform/modules/effects/src/effects_root_module.ts

Line 12 in 2bac73c

export const ROOT_EFFECTS_INIT = '@ngrx/effects/init';

However, it doesn't work with createReducer or createEffect

Should we create this action through createAction?

Can be done, the same way as pointed out in #2206
