ARTEMIS-1753 Prevent NPE on 1.x Client Topic Sub
When creting a durable topic subscription using the Artemis 1.x JMS client library. The client sends a QueueQuery to the server to see if the durable subsciption queue already exists. The broker then performs some transformation of the queue addresses to suit the 1.x naming scheme. However, if the queue does not already exist the transform is attempted on a null string causing NPE. To fix we simply check that the result return isExists=true.
