Add addtional common problem for cache reset (#3809)
When fresh installing `v2` branch some time getting issues with bundling. Due to `rn-packager` cache. Normal `npm start -- --reset-cache` was not working properly. So had to reset the cache manually. Maybe its because of the start script is different from regular react native app setup
