QPID-6272: [Java Broker] Null reference to AMQChannel#defaultQueue once the
queue is deleted
> Avoid leak potential for the 0-8..0-91 default queue
> ----------------------------------------------------

> AMQP 0-8..0-91 has a concept of default queue. This is the default queue to
> which operations such as basic.consume apply if the client chooses not to
> pass a queue argument within the command. The default queue is defined as
> the queue that is most recently declared, passively or otherwise by a
> queue.declare command.
> There is the potential for a leak in the current implementation of
> AMQChannel's default queue implementation. It retains a reference the queue
> that is the default even if the queue is deleted. It would be safer if the
> default queue reference is cleared if the queue is deleted (either explicitly
> by a queue.delete or the side effect of the cancelling of a consumer).
