[BUG] - ServiceBus - Exception throw when calling peek on empty queue

[andrewstevenson]

Calling peekMessages on an empty queue results in an exception. Expected behaviour was to return an empty iterable.

same for topics, I have to check if the subscription or queue has messages before calling :-(
