sync periodic_task fix from incubator

Set the value of time the periodic task was last run to a multiple of the
spacing value rather than the actual last time run. This ensures tasks runs
regularly but avoids synchronizing that interval with other nodes.

This patch also removes the coalescing of tasks which are _nearby_ (0.2
seconds away).
