title: Removing a node from Node-red
body: <p>I've installed the contrib-mssql node using npm -g.
  Now when I run npm uninstall the node is still listed in the left side bar. </p>
  
  <ul>
  <li>There are no flows using it and I can disable it in user settings/manage palette.</li>
  <li>Also I did not find anything referring to "mssql" in the settings.json of Red-Node.</li>
  </ul>
  
  <p>I like to get rid of the node. Any hints on what I could try next?</p>
