    cheese-camera: fix 2 gst object reference leaks
    
    Quote from the manual:
      http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstBin.html#gst-bin-get-by-name
      GstElement *gst_bin_get_by_name (GstBin *bin, const gchar *name);
      Caller owns returned reference.
    
    We get both colorspace1 and colorspace2 with gst_bin_get_by_name().
    We must unref both before exiting.
