title: Facebook restfb using jsonObject stopped getting likes count
body: <p>I am using restfb to get the number of likes in an specific post, and it was working well. Somehow, this morning it stopped working, and I didn't change anything in the code. 
  The problem is on the following line:</p>
  
  <pre><code>posts.get(i).getJsonObject("likes").getString("count"))
  </code></pre>
  
  <p>After retrieving the posts from a page, when trying to get the number of likes that this post has, I get this:</p>
  
  <blockquote>
    <p>com.restfb.json.JsonException: JsonObject["count"] not found.</p>
  </blockquote>
  
  <p>I used Graph API Explorer to see if my search was working and to check if "count" appeared on the results, and it does:</p>
  
  <pre><code>  "likes": {
      "data": [
        {
          "name": "Kobi Parfait", 
          "id": "100000605529126"
        }, 
        {
          "name": "John Foley", 
          "id": "100002480987029"
        }, 
        {
          "name": "Camilla Slima", 
          "id": "1267755442"
        }, 
        {
          "name": "Augustine Paz", 
          "id": "677044677"
        }
      ], 
      "count": 198648
    },
  </code></pre>
  
  <p>I don't understand what is going on, can someone help?</p>
  
  <p>Thanks in advance!</p>
