Groups are only available after reloading the page

[christianbltr]

After authenticating a frontend user, the frontend groups of this user are not available until the next request (page reload).

Example: The user is logged in by a matching IP, but cannot see e.g. content elements on the page which are available only for certain groups, although the frontend user has that groups assigned. After a page reload he can see the content elements.

The merge request #59 fixes the problem in our environment.
