[gnumeric] Introspection: fix Gnm.Range.init

[Morten Welinder <mortenw src gnome org>]

    Introspection: fix Gnm.Range.init
    
    This returns its first argument and, evidently, confuses introspection
    badly.  (skip) used to work, but we now need to rename a void-returning
    function on top.
