    tests: Fix bug in pixdata test
    
    In 3724a739 we added a test for the deserializing code, but we shouldn't
    be free'ing the contents straight away, as gdk_pixdata_deserialize()
    does not copy the data, but expects it to stay around until we've copied
    the data to the pixbuf (with gdk_pixbuf_from_pixdata() and copy_pixels
    == TRUE), or we're done with the pixbuf.
