Adjust previous jsonrpc change

(nth 2) is probably a better alternative to caddr, and in Emacs 26.1
we can pass 0 as :service to automatically find an available port.

* lisp/jsonrpc.el (jsonrpc--call-deferred): Use cl-caddr.

* test/lisp/jsonrpc-tests.el
(jsonrpc--call-with-emacsrpc-fixture): Pass 0 as :service to when
making the listen server.
