gtk: call launch after rom reset

Jan reports that if you call reset when a game is paused
the statusbar would wrongly report the game as playing
when it is actually paused. Jan's attached patch removes
the call to desmume_resume() and the status bar update.
I think the intent here is different and the plan was to
reload the game so just call Launch directly as already
Jan noticed it would do the right thing.

Based on a patch from Jan Bücken (nooris), #3288654
