app_queue: Made pass connected line updates from the caller to ringing queue members.

Party A calls Party B
Party B puts Party A on hold.
Party B calls a queue.
Ringing queue member D sees Party B identification.
Party B transfers Party A to the queue.
Queue member D does not get a connected line update for Party A.
Queue member D answers the call and still sees Party B information.

However, if Party A later transfers the call to Party C then queue member
D gets a connected line update for Party C.

* Made pass connected line updates from the caller to queue members while
the queue members are ringing.
