        Fix some uninitialized memory usage errors.  #427385

        * src/frame.c (meta_window_ensure_frame):
        * src/frames.c (meta_frames_manage_window):
        Do not try to set the window background in
        meta_frames_manage_window() since the frame window is not yet
        created and not yet registered with the corresponding MetaWindow.
        Do it inside meta_window_ensure_frame() instead.
