title: Airflow connection UI not visible
body: <pre><code>Airflow version: 1.10.2
  Ubuntu: 18.04 (bionic)
  Python: 3.6.5
  </code></pre>
  
  <p><strong>Issue:</strong> I am not sure how but the connections are not visible when I click Admin in the menu. Has someone ever faced this thing?</p>

  <p>When I edit the URL and go to localhost:8080/admin/connections I see the below response. This was working fine since </p>

  <p>But when I list the connections from airflow cli, it works. <strong>I am not sure why it is not visible on UI but rather accessible from cli? Or how should I give the UI user access to 'Connections'?</strong></p>
