js: allow optional Key retrieve pattern to be null

--

* src/Keyring.js: If the optional "pattern" parameter is not to be
  used, but another, following parameter is, null is more of a
  convention in javascript, thus both null and undefined are
  interpreted as "this parameter is not meant to be set".
