[gtk+] Fix fallout from g_object_ref change

[Matthias Clasen <matthiasc src gnome org>]

commit 072f06abf713d7536ce2a84a5ac266f585c88d39
Author: Matthias Clasen <mclasen redhat com>
Date:   Fri Dec 8 17:48:47 2017 -0500

    Fix fallout from g_object_ref change
    
    g_object_ref now returns the type of the object that was
    passed. Introduce cast as necessary to avoid warnings due
    to this.
