make differentiation between audio/video call if currentConversation is passed to CallNotificationController
right now differentiation is only done in "handleFromNotification".
But if currentConversation was already passed in, there has to be a differentiation between audio/video too.

```
        if (currentConversation == null) {
            handleFromNotification();
        } else {
            runAllThings();    // handleFromNotification not called so there is no differentiation. audio/video differentiation might have to be passed as another parameter into CallNotificationController
        }
```
