146's change is correct on a mesh being raised and fatal on one that is
running: the server will not move a push consumer's delivery subject
while a subscriber is bound, and a node is bound to its declaration
consumer the whole time it is up. Reproduced before fixing; an earlier
version of the test unsubscribed first and passed against the broken
code.
The consumer that works is kept and the assertion says so. Not re-made:
the nodes are granted the bare subject only, so re-making would have
silenced every machine.
