Stop emacsclient tests hanging (Bug#28319)

* test/lib-src/emacsclient-tests.el
(emacsclient-test-alternate-editor-allows-arguments): Use a
non-existent file to communicate with server, so that any existing
default server will not be hijacked (in fact, the test does
not need a server).
(emacsclient-test-alternate-editor-allows-quotes): Likewise.
