  Fix not stopping MOH when transfered local channel queue member is answered.
  
  The problem here is only present when local channels are used with the MOH
  passthru option as well as no optimization (/nm). I will describe the slightly
  bizarre scenario that was used to test, where phones B and C are queue members:
  
  Phone A dials into a queue with two members using local channels and the above
  options. Phone B answers. Phone A blind transfers phone B into the same queue.
  Phone A hangs up. Phone C answers, but phone B didn't stop playing MOH.
  
  In this scenario, the unhold frame that should have gotten to phone B never
  arrived due to the masquerade from the blind transfer. This is usually fine
  since app_queue manages the starting and stopping of MOH. However, with the
  passthrough option enabled when app_queue attempts to stop MOH it tries to do
  so on the local channel rather than the real channel. The easiest solution
  was to just make sure to send an unhold frame during the transfer since it
  wouldn't make sense to have MOH playing after a transfer anyway. This only
  modifies SIP transfers, but the other transfers did not seem to be a problem.
  If DTMF based transfers were a problem it might be okay to add ast_moh_stop
  to finishup, but I didn't want to have to add that unless required.
