Current behavior

useFactory for BASE_PATH_HREF is fired before useFactory for APP_INITIALIZER

Expected behavior

useFactory for APP_INITIALIZER should fire before BASE_PATH_HREF

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

I wan't to get a set of allowed basepath from the server before the app loads.
