this change is not necessary imo. both in ExecutionGraph and JobGraph,
scheduleMode is initialized to a proper ScheduleMode. setScheduleMode requires
a ScheduleMode as an argument, so there's no issue here aswell. only possible
problem i can see is passing null to setScheduleMode, but that's catched in the
switch statement anyway.
