(Temporarily) remove route_redirect_event eventhandler.
Such handler should pass different set of variables, instead of directly providing 2 locked route entries. Given that it hasn't been really used since at least 2012, remove current code. Will re-add it after finishing most major routing-related changes. Discussed with: np
