event-loop: Fix idle handler dispatch corner case

When the last idle handler queues another idle handler, we fail to
dispatch that last handler.  The wl_list_for_each_safe loop looks up
the next pointer before running the handler, and at that point it points
to the head of the list and the loop terminates.

Instead, just loop until the list is empty.
