js: return base64 after encrypt with armor=false

--

* src/gpgmejs.js/encrypt: the encrypted data were converted back to a
  (incorrect) string, whereas they should be data with no encoding
  specified. Returning base64 data is the expected way.
* DemoExtension: caught yet another usage of old syntax.
