    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.

    testsuite/gtk/defaultvalue: Actually build...& fix
    
    It looks like this got dropped during the move from autotools and never
    restored. I can see why, since making it work wasn't a hugely fun task!
    
    Notes on some less then obvious details:
     * PlacesSidebar is private now and didn't seem to be to be particularly
       easy to adapt to, so this moves to checking for it by name, not TYPE.
       I couldn't find a (fast) better way; if you know how, please clean up
     * added 2 casts to avoid warnings from the new type-propagating ref()
     * GdkClipboard and GdkContentProvider need some properties dodged
     * GtkToolItemGroup is gone
     * fixed indentation and used TypeName:property-name syntax in a print()
