    Fix txrecaptcha.submit() to always return Deferreds.
    
    All returned Deferreds callback with RecaptchaResponse objects. This
    way, we do not need additional code to check if the result was a
    Deferred (because, in that case, we would need to add a callback
    function to extract the RecaptchaResponse object from it and check it),
    or if it directly returned a RecaptchaResponse.
    
    This function now *always* returns Deferred.
