BACKUP: Fix Phone tip "backup has stopped" when backup mms to SD card

The send out mms's pdu type is Retrieve Conf, but the PduComposer didn't

Add Retrieve Conf support for PduComposer.

Check the unsupported type's uri to avoid NullPointerException

Make sure the uri has an authority before using it.
