[BUGFIX] Avoid crashing translators (Asterisk or FreeSWITCH) by instructing them to call back to terminated Call objects

This was occurring occasionally when deregistering calls from the translator because the ID (and channel for *) were not passed along with the instruction and so had to be queried from the Call.
