improve SchedulerJobsTest.testDateFormat() by introducing Awaitility

This recently introduced new test (FINERACT-926) would locally pass, but
then fail on the next run, because another test in the same class would
modify job state to be inactive.  It now sets the first jobs state as it
requires it to be, and properly awaits the expected outcome.
