app: apply the schedule when folders change

Scheduler.apply cancels the periodic job while no folder points at a
pinned remote and enqueues it once one does, so adding the first folder
or removing the last one changes what should be scheduled. The remote
and schedule editors already re-applied on save; this one did not, and a
user who left the app from this screen kept a job that could only fire
and refuse.
