Remove the scheduler queue lock.

Instead, use queue task_done calls to indicate that the scheduler
has finished processing events.  This lets the tests know when
the queues are both empty and all requests have been handled.

Add a lock around reporting complete events in fake jenkins jobs
so that waitUntilSettled can be assured that no new events will
arrive.

Directly report LOST builds when a job doesn't exist, rather
than spawning a new thread (which was only done to work around
the lock).
