stop_all_periodic_tasks skipping every other task

[mikado98765]

It seems like the logic for stop_all_periodic_tasks in bus.py removes each task from self._periodic_tasks as it goes through the loop. But if it removes and increments each time through it would skip every other task (if the remove_task flag is true).

You are right, this is not OK, since modifying a list while iterating over it results in unspecified order.

Hi all, is there a plan to include this fix in a 3.3.x version?
