title: Name and nickname returned are the same for group members
body: <p>This is my request code:</p>
  
  <pre><code>data = requests.get(
      f"https://api.groupme.com/v3/groups/{group_id}?token=token123"
  ).json()['response']
  </code></pre>
  
  <p>Which returns something along the lines of this:</p>
  
  <pre><code>"members": [{
    "name": "Capn Jack",
    "nickname": "Capn Jack"
  }]
  </code></pre>
  
  <p>I was originally receiving an output like this, which I would expect:</p>
  
  <pre><code>"members": [{
    "name": "Jack Doe",
    "nickname": "Capn Jack"
  }]
  </code></pre>
  
  <p>Does anyone know why the api wouldnt be returning the proper name for the member in my group? Is there anyway to get a consistent name for members of a group that isnt affected by a nickname change?</p>
