users/logout controller/action combination requires valid session

The users/logout controller/action requires a valid session but should not.

To reproduce for example with a clean browser go to

https://comanage.sphericalcloud.net/registry/users/logout

You will be redirected to 

https://comanage.sphericalcloud.net/registry/users/login

and then to

https://comanage.sphericalcloud.net/registry/auth/login
