title: Spring Social Facebook email null
body: <p>I try to integrate spring social facebook to my project (i already have managed to integrate google+ and twitter signin). The problem i have is with facebook provider which returns null for the most values. I use below code:</p>
  
  <pre><code>Connection&lt;Facebook&gt; fb_connection = (Connection&lt;Facebook&gt;) providerSignInUtils.getConnectionFromSession(request);   
  fb_connection.getApi().userOperations().getUserProfile().getName();//i get the name
  fb_connection.getApi().userOperations().getUserProfile().getId(); //i get the id
  fb_connection.getApi().userOperations().getUserProfile().getEmail(); // email and all other values are always null
  </code></pre>
  
  <p>I tried many versions of spring social facebook right now i use 2.0.0.M1 which i think is the latest.
  Below is the signin form i use:</p>
  
  <pre><code>&lt;!-- FACEBOOK SIGNIN --&gt;
  &lt;form name="fb_signin" id="fb_signin" action="&lt;c:url value="/signin/facebook"/&gt;" method="POST"&gt;
      &lt;input type="hidden" name="scope" value="email,public_profile,user_friends" /&gt;
      &lt;button type="submit"&gt;Facebook&lt;/button&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>Any ideas?</p>
