What is the current behavior?

After converting angular-advanced-seed to use @ngrx v4, the multilingual service which uses @ngrx to handle language state change works just fine.

When expanding the seed with additional modules, components, reducers and effects, the multilingual module fails to handle initial translation properly because the multilingual effect associated with language change action is not initially triggered due to timing issue : the change language action is dispatched before the multilingual effect is instantiated and ready.

Expected behavior:

Expanding an application should not affect instantiation of effects or action dispatch should wait for all effects to be ready for use.

Minimal reproduction of the problem with instructions:

Version of affected browser(s),operating system(s), npm, node and ngrx:

see issue #351

Other information:

using setTimeout to delay the initial dispatch of the change Language action for browser language fixes the issue but is not safe.
