Change subject: app_queue.c: Force COLP update if outgoing channel name changed.
......................................................................


app_queue.c: Force COLP update if outgoing channel name changed.

* When a call is answered and the outgoing channel name has changed then
force a connected line update because the channel is no longer the same.
The channel was masqueraded into by another channel.  This is usually
because of a call pickup.

Note: Forwarded calls are handled in a controlled manner so the original
channel name is replaced with the forwarded channel.
