js: typecheck destructured parameters

--

* destructuring just takes the input argument and treats it as object.
  In cases like in src/Keyring/generateKey, where I forgot to change
  the old syntax, the fingerprint as string was destructured into an
  object without "pattern", which caused all Keys to be retrieved.
  So, methods with a destructuring now check if the first argument is
  an object and get a default empty object if no parameter is
  submitted. This allows the further use of destructured parameters,
  while still ensuring nothing vastly incorrect is used.
* src/Kering.js, unittsets.js: fixed old syntax in method usage
