Draft: kcms/nightcolor: Hack to workaround settings change signals not working
In systemsettings6 (but not kcmshell6), it seems like onActiveChanged for kcm.nightColorSettings sometimes doesn't get called
when it should. This is a workaround for this problem.
I'm making this MR more to invite discussion from people knowledgeable about KF6 changes to systemsettings into what might be the underlying cause. I dislike this hack actually, so it is marked as a draft.
