title: redis module for nodejs does not save if expiry is set
body: <p>If I don't set the expiry it does work</p>
  
  <pre><code>client.set('key', 'val');
  </code></pre>
  
  <p>But this one below does not save to redis.</p>
  
  <pre><code>client.set('key', 'val', 'EX', 3600);
  </code></pre>
  
  <p>I think it was working before.</p>
