Proper redirect after logging in with TLS

[RubenVerborgh]

#650 broke logging in with TLS without popup, as it now doesn't redirect anymore

@timbl The problem is actually on your side: https://timbl.com/login is outdated.

The correct source is in default-views/auth/login.hbs. On installation of the server, default-views/ is copied to config/views. I actually have config/views symlinked to ../default-views.
