title: Mongo-Express not showing all DBs with root admin
body: <p>I am having a bit trouble setting up mongo-express with my local mongodb install. Basically, I created an admin user like this:</p>
  
  <pre><code>  db.createUser(
     {
         user: "admin", 
         pwd: "abc123", 
         roles:["root"]
     })
  </code></pre>
  
  <p>And in mongo-express's config.js I specified this account for the authentication. Running <code>mongo-express -u "admin" -p "abc123" -d "admin"</code> works, and opening the webview shows the admin database. </p>

  <p>But that is the only DB it shows there, but I have more DBs within mongodb:</p>
  
  <pre><code>&gt; show dbs
  admin     0.000GB
  local     0.000GB
  test      0.112GB
  </code></pre>
  
  <p>I want the <code>test</code> DB to show up there as well, but I do not understand whats preventing mongo-express from displaying it. I do understand that authentication happens at DB level, but since the admin was created with <code>root</code> as role, mongo-express should be able to display all DBs, right?</p>
