idle-monitor: Postpone dispatching of idle timeout if not ready

If we update the ready time while the source is already in the
to-dispatch list, changing the ready time doesn't have any effect, and
the source will still be dispatched. This could cause incorrect idle
watch firing causing the power management plugin in
gnome-settings-daemon to sometimes turn off monitors due to it believing
the user had been idle for some time, while in fact, they just logged
back in.

Fix this by not actually dispatching the idle timeout if the ready time
is in the future when actually dispatching.
