The simulator names changed after updating to Xcode 10.2 (iOS 12.2 SDK)

* Add a React Native alias, and one to start the web server
* Reorganise aliases in react-native plugin
* Update README for react-native plugin:
Fix format and add a brief description
Add missing aliases in react-native plugin README
