Fix race condition in bgw_db_scheduler

Browse Source 
The regression test bgw_db_scheduler tests if the BGW scheduler starts a
background job after it is created. However, this only happens if the
previous instance of the BGW scheduler is no longer active. If the old
BGW scheduler instance is still running, it will pick up the job and
prevent it from starting in the current test.
