Logout endpoint tries to render non-existent view in some cases

[davexunit]

The end of the logout endpoint code in lib/casserver/server.rb, there's the following if block:

      if @gateway && @service
        redirect @service, 303
      elsif @continue_url
        render @template_engine, :logout
      else
        render @template_engine, :login
      end

The middle condition attempts to render a view that doesn't exist. Is this intentional? Are users expected to write a custom logout view? If not, would it make sense to redirect to @continue_url instead?
