    Avoid GtkCellArea critical warnings in thumb view
    
    GTK+ switched from using constructor() to constructed() in GtkIconView,
    which exposed that Cheese does not chain up in the CheeseThumbView (a
    GtkIconView subclass) constructed() vfunc. Chain up at the start of
    constructed() so that the construct-only properties of the GtkIconView
    are set before calling icon view API.
