QPID-4159: HA Missing messages in failover test.
QueueGuard was taking its snapshot of the initial queue range *before* it
registered its QueueObserver. That means it was possible to have unguarded messages
between the end of the snapshot and the first position protected by the guard.
Fixed race condition in QueueRange constructor: Must call getPosition() *after*
getFront() since both may be advancing and we want to end up with a valid range
front <= back+1.
