    google: Drop the (GDestroyNotify) cast
    
    "warning: function called through a non-compatible type" is printed
    by GCC 8 because of (GDestroyNotfiy) cast in g_clear_pointer, see for
    more info: https://gitlab.gnome.org/GNOME/glib/issues/1425. Let's
    drop the (GDestroyNotify) cast in order to prevent those warnings.
    The cast was not needed anyway.
