Remove no longer needed broadcasts

Removed broadcasts that were sent from the framework
to Managed Provisioning during DPM#createAndProvisionManagedProfile
and DPM#provisionFullyManagedDevice to handle system apps
snapshotting. This is no loger needed as Managed
Provisioning is directly applying that logic after calling the APIs.
