core: Fix QuartzException when Ctrl+C engine

When shuting down engine in dev environment using Ctrl+C
exceptions are printed to the screen because of Quartz shutdown.
This patch validates that the scheduler can indeed reschedule a job before rescheduling it.

Exception Dump is:
failed to reschedule the job: org.quartz.SchedulerException: The Scheduler has been shutdown.
