title: Meteor trying to get Facebook details
body: <p>I am trying to get the user birthday and user location.</p>
  
  <pre><code>Accounts.ui.config({
    requestPermissions: {
   facebook: ['user_birthday', 'user_location'],}});
  </code></pre>
  
  <p>When I sign in with facebook, it does ask me for the permissions for these.</p>
  
  <pre><code>var service = _.pairs(user.services)[0];
  var serviceName = service[0];
  var serviceData = service[1];
  </code></pre>
  
  <p>All my facebook details are retrieved from serviceData but birthday and location are not there. Can anyone help? Thanks</p>
