Mattermost marking users "offline" when they are "away"

@jasonblais,

  1. Since installation. And i even installed on a different VM and still does the same.
  2. All users (51) have the same problem.
  3. I use NGINX as proxy

Just to remember we receive the message and notifications correctly. The only thing is the icon changing for the wrong status, in this case to offline icon when should be away icon.
