    display-config: Do not invert order when constructing modes
    
    Mutter sends modes in descending order of preference. By reverting
    the order via `g_list_prepend`, we get unintended side effects
    such as choosing the least preferred refresh rate by default (if
    the selected mode is not marked as preferred).
    
    Instead of adding complex logic in several places, make sure that
    the assumption of descending preference is kept by simply not
    inverting the order.
