js: fixing errors found by testing: encrypt/decrypt

--

* Key.js: Error code for wrong parameter in createKey should be
  "PARAM_WRONG"
* Helpers.js: The property openpgpjs-like Objects were checked for in
  toKeyIdArray was not defined.
* src/permittedOperations.js: updated more expectations and assumptions
  for the native API

* new Problems:
  - There seems to be a message size limit of about 21 MB for
    nativeMessaging, much lower than the documented 4GB.
  - Some bytes are lost with random data in an encrypt-decrypt
    roundtrip. The culprit is unclear.
