Fix: avoid extra depsgraph evaluation when stopping animation playback

The `NC_SCENE | ND_FRAME` was originally added so that the sequencer
preview is redrawn so that the fps stops showing (2855485565).

Using this specific notifier has the side effect that it also causes a depsgraph
update in `wm_event_do_notifiers`. However, that is not necessary just to
trigger the redraw. Using the `NC_SPACE | ND_SPACE_SEQUENCER` notifier
also triggers the redraw without causing a depsgraph update.
