Use a different timesource in recurrent timer.

Previously we used elapsedRealtimeNanos in recurrent timer which will
still go even if the system is in deep sleep. This causes all the
events "happened" during suspension to be replayed immediately
after the wake up, which causes a spam of messages. uptimeNanos
meanwhile, does not go if the system is in sleep, so we use that
instead.
