Description

While investigating QPID-4262, discovered via code review that the PriorityQueue does not properly update its backing "fifo" MessageDeque's available count when PriorityQueue::removeIf is invoked.

This might prevent the deletion of a queue and might result in queue listeners being woken up unnecessarily.
