After automatic lazy login, message should not be displayed

[mitar]

After automatic lazy login, message should not be displayed? Or it should? Currently it is as internally user is really logged in into a new automatically created account. This message could confuse user. But also maybe warn her that she is using the site as lazy user if she maybe have real user?

Maybe just message could be improved in such case? "Logged in as temporary user." or something.

Authentication has moved to separate package, so this should be implemented there: mitar/django-mongo-auth#8
