ctdb-tests: Handle interactions with monitor events

In the first case, reconfiguration can longer happen in a monitor
event, so this is no longer a problem.  Drop it.

Running a monitor event by hand no longer cancels the existing monitor
event.  Instead the hand-run event fails.  So do this differently and
just wait for a monitor event before continuing.
