[gtk/gtk-3-24: 1/2] Fix GPtrArray sorting function

[Matthias Clasen <matthiasc src gnome org>]

commit 6a507c0b63993bfd5d72ce24984cdc8c57caa874
Author: Tristan Partin <tristan partin io>

    Fix GPtrArray sorting function
    
    GPtrArray's GCompareFunc passes a double pointer that needs to be
    dereferenced in order to use the data you are actually wanting to
    compare.
    
    See: https://developer.gnome.org/glib/stable/glib-Pointer-Arrays.html#g-ptr-array-sort
