title: Spring social twitter, fetched profile returns null email (app whitelisted)
body: <p>I'm trying to add "Sign in with Twitter" thing to my web application. I configured spring security and social and everything works i.e. I can fetch user name, access key, secret etc., but when I want to get user email from fetched profile I'm getting null. </p>
  
  <p>My code inside of controller (spring redirect to this after successful authorization) looks like this:</p>
  
  <pre><code>Connection&lt;A&gt; connection = providerSignInUtils.getConnectionFromSession(request);   
  String email = connection.fetchUserProfile().getEmail();
  </code></pre>
  
  <p>I know you have to whitelist application, check "Request email addresses from users" field, refresh tokens etc. I did that all already and still getting null. I'm out of ideas what to do, I tried "/auth/twitter?scope=email" instead of "/auth/twitter" but does not work. Maybe it's something wrong with Spring?
  I'm using newest spring-social 1.1.4 with spring twitter API 1.1.2.</p>
  
  <p>I saw many question about this issue but all of them were from 2011/2012, AFAIK Twitter didn't support fetching email address from user back then, but it changed, however it still doesn't seem to work properly.</p>
