title: UIDocumentInteractionController shows "copy to" along with another entry for same app
body: <p>I bring up a UIDocumentInteractionController like this:</p>
  
  <pre><code>self.documentInteractionController = [[UIDocumentInteractionController alloc] init];
      _documentInteractionController.delegate = self;
      _documentInteractionController.UTI = kUTTypeMPEG4;
      _documentInteractionController.URL = aURL;
  
      dispatch_async(dispatch_get_main_queue(), ^(){
          [_documentInteractionController presentOpenInMenuFromRect:CGRectZero inView:view animated:YES];
      });
  </code></pre>
  
  <p>The resulting UIDocumentInteractionController has plenty of duplicate entries.</p>
  
  <p>e.g. "WhatsApp" and "Copy to WhatsApp", "Slack" and "Copy to Slack",...</p>
  
  <p>Is there any configuration I have missed to avoid that?</p>
  
  <pre><code>[UIDocumentInteractionController presentOpenInMenuFromRect:]
  [UIDocumentInteractionController presentOptionsMenuFromRect:]
  </code></pre>
  
  <p>Reading the docs it seemed to me <code>presentOpenInMenuFromRect:</code> might be more limited by showing only apps capable of opening the file - but both methods show the same duplicates.</p>
