Android: PlatformServices:Do not expect Intents in non-Activity usecase

In non-Activity contexts, do not register the QPlatformServices class
as an intent listener, as only Qt applications based on Qt Activities
will receive new Intents. Calling getIntent on a non-Activity context
will also cause an error, as getIntent is a method of Activity, not
Context.

Skip both when constructing QPlatformServices for applications without
an Activity context.
