Ensures listener queues exist in fake driver

The fanout queues of the fake driver are created at the first executor
poll, but if we use eventlet executor and the fake driver, when the sender
delivers a fanout message before the first poll, the message goes to the
topic queue instead of the server fanout queue.

The changes fixes that by ensuring the all queues exists when the
listener is created.

Closes bug #1331453
