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

> Key: QPID-5798

> Project: Qpid
> Issue Type: Bug
> Components: Java Tests
> Affects Versions: 0.26
> Reporter: Andrew MacBean
> Attachments:

> Original Estimate: 4h

> 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.
