QPID-3045 - sporadic failure of cluster_tests.ShortTests.test_route_update
Sporadically the test was failing because the session associated with
an inter-broker bridge was created out of order with other
objects. This is unlikely to cause a fatal cluster inconsistency in
practice but it has been corrected in any case. The fix was to delay
creation of the management object for a bridge session till a point
which is consistent on all cluster members.
