Log:
QPID-3440: add test to verify issue by ensuring that the reply-to Destination
cache results in use of the same Destination objects for subsequent messages.
Implement equals() and hashCode() for the generated ReplyTo class to let it
function properly as an index in the hashmap to resolve the issue. Update
PropertyValueTest to remember the initial reply-to destination it sets and
compare it with the value returned after sending/receiving the message, rather
than constituting its own test destination for comparison.
