    app: sync tests with gimp-2-10.
    
    Commits e70c08cdd01dcae7117f880dfc286e178fe4a262 from mitch and mine
    (5335f313d97f65a3f8f8f21159e6bd7c699f67d2) clashed as we did the same
    fix nearly the same time on both branches. Let's at least sync so that
    the code is exactly the same (just to avoid potential merge conflicts in
    the future).
