Update ExternalStorageProvider volumes with StorageEventListener
We were listening to volume state changes in the
ExternalStorageProvider with the VOLUME_STATE_CHANGED broadcast in the
MountReceiver.
This broadcast can be severly delayed especially on user startup so we
also listen with the StorageEventListener which is more performant.
