[application] call req.set_session in application.main_handle_request
The Session handling chain is no more responsible for calling req.set_session.
It just returns a valid session and lets the caller link it to the Request.
This opens the way to explicitly creating and closing a connection/transaction
in ``application.main_handle_request``.
