Issue wix#525, changed the conditions for InvalidNotificationException

To fix issue wix#525 (wix#525), I did 2 changes below. 

``` 
    @OverRide
    public void onReceived() throws InvalidNotificationException {
        // 1. removed the following if/else statement
        // if (!mAppLifecycleFacade.isAppVisible()) {
        //     postNotification(null);
        //     notifyReceivedBackgroundToJS();
        // } else {
        //     notifyReceivedToJS();
        // }
        
        // 2. added the following 2 statements, instead of the if/else statement above 
        postNotification(null);
        notifyReceivedToJS();        
    }
```
