    Don't wrongly fall back to shotwell developer
    
    If we requested CAMERA development, but the RAW file did not have any
    preview embedded, Shotwell falls back to the SHOTWELL developer, even
    though we have the camera-developed fle available
    
    Only fall back to SHOTWELL if embedded was chosen and embedded is not
    available.
