[login] redirect to real instance root if no postlogin_path is provided
When not postlogin_path is provided, the login form issue a redirect to "/".
The instance root may not be at "/" on the server. Then issuing a redirect to
"/" send the user to the wrong location.
We now redirect to "." which works fine because the "login" controller a direct
children of instance root (http://babar.com/instance/login).
All other redirection of the login controller use relative path too and then
rely on this relative path from the login controleur to the instance root. This
mechanism may be considered fragile and may deserve a proper fix. but this is to
be discussed and implemented in another changeset.
