Description

Fixing issue DISPATCH-1708 reveals another problem.

Test_28 fails with

63: ======================================================================
63: FAIL: test_28_switchover_local_edge_alt_remote_edge (system_tests_fallback_dest.RouterTest)
63: ----------------------------------------------------------------------
63: Traceback (most recent call last):
63:   File "/home/chug/git/qpid-dispatch/tests/system_tests_fallback_dest.py", line 297, in test_28_switchover_local_edge_alt_remote_edge
63:     self.assertEqual(None, test.error)
63: AssertionError: None != 'Timeout Expired - n_tx=256, n_rx=0, n_rel=111117, phase=1, local_rel=1246'

Apparently the fallback dest receiver router EA1 is never notified that the primary receiver on router EB1 has exited. EA1 then keeps sending messages for the test to INT.A where they are released.
