The order of sub-apps (order of the tabs) can be changed by URI or favorite, if the app was not open before.

To reproduce

• make a favorite for the sub-app "roles", which is usually shown on last position (4th), if you just open the security-app.
• close the sec.-app and call the sub-app "roles" with the favorite-link.
  => now "roles" will be on the 2nd place.

Every time when an app is closed and you call a sub-app with a location-link, the subapp of the location-link will be rendered always on the 2nd place (if its not the 1st by definition)
