emit `movingstarted` on each loop

[kfarr]

I'm not sure if this is desired behavior but it made sense for my project and seemed like was missing in this component. Current behavior when loop is true, movingended is emitted each loop, however movingstarted is only emitted once at the start but not at each loop. By removing moveonpath state upon a loop completion this now results in movingstarted being emitted each loop.
