The test tried to start a replica whose box.cfg would hang, with
replication_connect_quorum = 0 to make it return immediately.

But the quorum parameter was added and removed during work on
44421317 ("replication: do not
register outgoing connections"). Instead, to start the replica
without blocking on box.cfg it is necessary to pass 'wait=False'
with the test_run:cmd('start server') command.

Closes #5311
