[BUGFIX] Fixed cancelMenu sound not playing after switching state

[AppleHair]

So in StoryMenuState and OptionsState, the cancelMenu sound doesn't play when coming back to MainMenuState, and in MainMenuState, the cancelMenu sound doesn't play when coming back to TitleState. This happens because MusicBeatState's startOutro runs FunkinSound.stopAllAudio, which means every sound played before the call to FlxG.switchState, which calls startOutro, will be stopped. To fix this, instead of calling FunkinSound.playOnce BEFORE FlxG.switchState, we call it AFTER FlxG.switchState. Easy!
