This reverts commit c8dd9233.

Due to the NGINX rewrite appending a "/" on URLs, the post-login
URIs are also given a trailing slash in. This made them invalid.
Now, clients generated with the init-db command are given
post-logout-redirects for both with and without a trailing slash.
Thus redirect after login works correctly now, and doesn't
bring you to steering-login (but to dashboard).

Fixes meta#94
