title: Dooekeeper authorize loses params after sign in
body: <p>I am using doorkeeper and devise, clicking the following link </p>
  
  <pre><code>localhost:3000/oauth/authorize?client_id=37ba9a06dd5e09c9be0332d5d977bcaaa64bae1f585f4aa898d1a3c5c34a2098&amp;redirect_uri=http://localhost:3001&amp;scope=info&amp;response_type=token
  </code></pre>
  
  <p>cause me to  get the token if i am already logged in, but if i am not logged in i got redirceted to users/sign_in (devise view) as usual, and after login it sends me to </p>
  
  <pre><code>   localhost:3000/oauth/authorize
  </code></pre>
  
  <p>without any params.
  I wont be able to get the token and doorkeeper displays the following error: The authorization server does not support this response type caused by the missing of response_type params.
  Any idea about what i need to check?</p>
