I decided to call `commValdationModule.validateMessageTypes` in `sqlite-data-handler.js` for testing purposes. So the test plan is:
1. Build the app
2. Apply this diff: https://gist.github.com/marcinwasowicz/dc64fde8c1ab67aeeabdcfce8008565d
3. Open the app. Ensure the warning message like this is visible:
```
Object {
"message": "MessageSpec not implemented in C++ for message types: ADD_MEMBERS, REMOVE_MEMBERS, LEAVE_THREAD, JOIN_THREAD, TOGGLE_PIN, ",
}
```
