title: Parse findInBackground does not work
body: <p>The find on the db does not complete, so the FindCallback.done() method is never called, no errors, nothing, just is not called. this is the code</p>
  
  <pre><code> ParseQuery&lt;ParseObject&gt; pq = ParseQuery.getQuery("Category").setLimit(1);
      pq.getFirstInBackground(new GetCallback&lt;ParseObject&gt;() {
  
  
  
          @Override
          public void done(ParseObject object, ParseException e) {
              throw new RuntimeException();
  
          }
  
  
  
      });
  </code></pre>
  
  <p>I can see the prints before and after this portion of code, but the exception is never thrown. Please, I do really need help.</p>
  
  <p>Edit: I use the parse-login before this point and it works correctly, even the saveInBackground() works correctly, the only problems I find are about queries, (find, getfirst ecc).</p>
