Improve "Queue not found" exception handling

In the case queue was disapeared during reconnection process, "Queue not
found" exception may break consumption in other queues, thus rpc subsystem
may got stuck.

Added a new method _try_consume() to consume queue. If queue is not found,
this method reconnect queue (this supposes to re-create a lost queue),
and try consume it one more time.
