title: chrome.management.getAll does not return Chrome Store's app data
body: <p>I am now writing a new tab page replacement for Chrome 33.</p>
  
  <p>While I am using <code>chrome.management.getAll()</code> to get app list, I found a strange thing.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>document.addEventListener('DOMContentLoaded', function () {
  ...
      chrome.management.getAll(getAllApps);
  ...});
  
  function getAllApps(data) {
  ...
      console.log("Installed App Count:" + data.length);
      for (var i = data.length - 1; i &gt;= 0; i--) {
          console.log("Found App: " + data[i].name + " type:" + data[i].type);
          if (data[i].type == 'theme' || 
              data[i].type == 'extension' ) {
              continue;
          };
      ...
      }
  }
  </code></pre>
  
  <p>The output never lists Chrome Store. </p>
  
  <p>But if I use <code>chrome.management.get()</code>, I could get the record of Chrome Store by its id.</p>
  
  <p>Is there anything wrong in my code? Or is the Store is intended to be hidden?</p>
  
  <p>Thank you. It is my first question here, so if there is any inappropriate words in my question, please forgive me.</p>
