Social Authentication is broken in OpenAM 12.01.
you see the result of the /json/authentication post call instead of getting redirected to the profile page (or the goto if you have specified one)
Steps to reproduce:
1. configure Google for social authentication and set it up as the default chain in a subrealm
2. start incognito window, navigate to AM login page of the subrealm
3. you get redirected to Google
4. Login at google
5. You get redirected back to OpenAM but only see the result of rest call in the browser
