Fix some crashes from bad datastore handling in app_queue.c

* The queue_transfer_fixup function was searching for and removing
  the datastore from the incorrect channel, so this was fixed.

* Most datastore operations regarding the queue_transfer datastore
  were being done without the channel locked, so proper channel locking
  was added, too.
