ARTEMIS-2013 Can't create durable subscriber to a composite topic
An OpenWire client can use a compound destination name of the form
"a,b,c..." and consume from, or subscribe to, multiple destinations.
Such a compound destination only works for topics when the subscriber
is non-durable. Attempting to create a durable subscription on a
compound address will end up with an error.
The cause is when creating durable subs to multiple topics/addresses
the broker uses the same name to create internal queues, which
causes duplicate name conflict.
