js: add tests

--

* BrowserTestExtension/tests:

  - decryptTest.js: Check Decryption and return values of binary data
  - encryptTest.js: Return data type of armored/non-armored encryption
  - added a small encoded input png for testing

* DemoExtension/maindemo.js: Fixed unexpected usage of the Demo encrypt
  (non-armored)
