 Review comment:
   Need a test case where a temporary dest is created first and then later 
consumers are created on it, currently with this change the existing behaviour 
which allows  this and will mean on create consumer for the temp dest will 
throw error as will be not a known dest.

> This is the client-side version of ARTEMIS-2449. Simply put, there is no 
> limit on the destination cache for a core JMS client. For a long-lived 
> connection sending to lots of different destinations (e.g. in a request-reply 
> use-case involving temporary queues) this can present a significant problem.
