Summary:Motivation: Developer expects `onclose` to be called before/during close of the websocket. The `websocketFailed` event triggers a close but does not invoke onclose.
Testplan: Connect to a websocket server from android, terminate the server, observe that onerror is called, the websocket is closed, but onclose is not called.
Note: the observed bug is in android only because in iOS the underlying websocket implementation fires the `websocketClosed` rather than `websocketFailed` event when the server terminates. Nevertheless, the justification for this change stands that regardless of the cause of the close, if `this.close` is called it is expected this.onclose should be called as well.

Summary: Check that the WS state is set to OPEN before trying to close it when the ```websocketFailed``` event fires. Otherwise the app throws an error at the Android level.

Summary: The JavaScript code for Android is same as the iOS counterpart, I just added few new lines and used arrow functions instead of binding `this`.
