`unprotectNeedReschedule()` will change job state to
`JobState.NEED_SCHEDULE` without `logOpRoutineLoadJob`.If job is paused
then rescheduled and paused finally, the record of two consecutive edit
logs will be 'PAUSED', the correct
replay sequence should be: `PAUSED` -> `NEED_SCHEDULE` ->` PAUSED`. 

Therefore, it is need to write edit log when rescheduled job.
