Steps to reproduce:
- Create a new user (U1)
- Go to U1's profile page
- Click on the green Follow button
Expected results: A user can follow another user (so he can then get messages from that user eg. http://test.xwiki.org/xwiki/bin/view/Message%20Stream%20Tests/Send%20Message%20To%20Followers)
Actual results: The Follow button doesn't appear anymore.
