https://issues.apache.org/jira/browse/AMQ-3607 - added test case and use of connectionFactory.setOptimizeAcknowledgeTimeOut, the test is breaking becauee of message discarding when the acks are not immediate, made some small mods to make the test work and fixed up the setter for connectionFactory.setOptimizeAcknowledgeTimeOut
