Boxes: drop RHBZ #1692972 workaround, fix for 
    
    RHBZ #1692972 was fixed long ago, so we don't need to worry
    about that any more. But this test failed on the recent F31 live
    respin compose because it was changed to assume the tutorial
    would appear on startup, which only happens on F32+. To make the
    test work on F31 respins, let's handle both paths. Once F32 is
    stable we can drop this as we won't run the test on F31 any more
    after that.
