Dokku deployment CHECKS don't work

[mattiasgrenfeldt]

I removed the previous CHECKS file in #3 since it made deployment fail.
This was the content of the CHECKS file:

/ datasektionen

This was the result when deploying:

       CHECKS expected result:
       http://localhost/ => "datasektionen"
       Attempt 1/5. Waiting for 5 seconds ...
remote:  !     
remote: curl: (22) The requested URL returned error: 400 BAD REQUEST

This happens since / redirects to login.datasektionen.se with a callback that doesn't match *.datasektionen.se.
