    open-selector: Fix crash introduced in GDateTime port
    
    commit acf14cc04f1e66c4c726d9a0b193bf39a28ca8b0 moved FileItems
    over to using GDateTime instead of GTimeVal.
    
    This reduced code complexity pretty nicely, but it unfortunately
    introduced a bug, where the sort_items_by_mru function was treating
    the FileItems themselves as GDateTime objects. That bug causes a
    crash when opening files.
    
    This commit fixes the problem by using the ->accessed members
    instead of the file items themselves.
    
    Closes: https://gitlab.gnome.org/GNOME/gedit/-/issues/465
