Fixes #4189@4h Route Duplication

* Duplication of Route is triggered by link and UI forwarded to edit of duplicatee

     - Changing route, only POST duplicate_referential_line_route --> RoutesController#duplicate
     - Removing route       GET  duplicate_referential_line_route --> RoutesController#duplicate
     - Removing controller action RoutesController#post_duplicate

* Link in Route Decorator depends on new policy RoutePolicy#decorate?

* Adapting specs
