Patch to add an AMQSession.sync() call for the non transacted acknowledgment mode cases to
avoid potential race condition and subsequent test failure.

> The test org.apache.qpid.client.failover.FailoverBehaviourTest.testAutoAcknowledgedQueueBrowserCloseWhileFailover
is intermittantly failing under the BDB 0-9 profile.
> The issue appears to be that the prepareQueueBrowser() method fails to take into account
that without a forced sync (for non transacted ack modes) there is a race between the producerSession
and the queueBrowsers check for the messages on the broker.  Adding a sync for the non transacted
ack mode cases should resolve this.
