messes things up when queuePrefix set to ""

Suppose my queue is EM_TRADE.Q and I force the messages to go to DLQ say sender.setTimeToLive(500);

If I have a queuePrefix="", it will turn both
EM_TRADE.Q jmx attribute DLQ = 'true' (This is incorrect)
EM_TRADE.Q.SuffDLQ jmx attribute DLQ = 'true' (This is correct)

If you did not assign queuePrefix at all it will default add ActiveMQ.DLQ in front queuePrefix="" is the only way to have the DLQ with nothing in the prefix.
