comment out /instant from controller/root.pm
Check but silently ignore failure of action token requirement for logout

Since the most common cause of an invalid action token in this case is
an expired session, simple redirect to / and it will reflect the session
invalidation.

This still prevents construction of a working '/logout' url.
remove all mentions of /instant -- no longer needed
Reinstate URL encoding for redir url parameter.
