A few conference calling fixes:
1. b/28325313 - When an SRVCC occurs, ensure that a phone account handle is set on
the GsmConnection which is added to Telecom. Also ensure that the
PROPERTY_CONFERENCE bit is set on the connection to ensure that the
InCall UI can display the correct label.
2. b/29059073 - Handle case where a video call is downgraded to an audio
only call, and thus should be able to be merged into a conference.
