title: Facebook Lead Ads API missing adset_name
body: <p>I am using the Facebook API package to receive detailed information about a new lead from Facebook Lead Ads.</p>
  
  <p>When I use the below</p>
  
  <pre><code>$lead = new \FacebookAds\Object\Lead('77408XXXXXX0968');
  $lead-&gt;read();
  
  $lead_data = $lead-&gt;getData();
  </code></pre>
  
  <p>This returns </p>
  
  <pre><code>Array
  (
  [ad_id] =&gt; 
  [ad_name] =&gt; 
  [adset_id] =&gt; 
  [adset_name] =&gt; 
  [campaign_id] =&gt; 
  [campaign_name] =&gt; 
  [created_time] =&gt; 2016-09-20T11:33:50+0000
  [custom_disclaimer_responses] =&gt; 
  [field_data] =&gt; Array
      (
          [0] =&gt; Array
              (
                  [name] =&gt; full_name
                  [values] =&gt; Array
  </code></pre>
  
  <p>But things like the adset_name are empty. Does anyone have any idea why or how I can populate them?</p>
