javascript/core: Allow clients to use trailing undefined args/cb

Fixes and tests: https://github.com/vanadium/issues/issues/715

The goal was to still allow us to have the undefined cb while also
having the undefined trailing arg. This CL addresses the accidental
assumption that a trailing undefined was always a cb and tests that
case in test-js-client-server.js
