js: use version operation for connection checks

--

* src/Connection.js: isConnected was renamed to checkConnection, that
  returns a promise with either version information or Boolean
* Connection checks have been adapted to reflect that checkConnection
  returns a Promise
* BrowsertestExtension: tests/signTest.js was missing from my last
