How to reproduce:
- log into enduser
- hit the red button Cancel on the bottom
- you are redirected to an empty page (see screenshot attached)
Cancel should be equivalent to Logout (so it is really needed? The logout button is already there).
Incidentally, the same pointless page is returned when accessing /syncope-enduser if authenticated - which looks wrong, the excepted landing page should be first one, e.g. "crendentials".
