Summary:
There was a reflective call to a non-existent class. It did, however,
exist in the template, so I copied it over from there and updated
the references accordingly.

Test Plan:
Built it and ran it. Works again with the latest Flipper desktop app.

Summary:
This diff formats the Java class files inside xplat/js/react-native-github. Since google-java-format was enabled in D16071401 we want to codemode the existing code so that users don't have to deal with formatter lint noise at diff-time.

Summary: This diff moves the React Native template from `local-cli/templates/HelloWorld` to `template`. Keeping it in the react-native repo will allow us to make changes to the template and version it together with react-native, instead of moving it out into a separate repo and trying to keep the template in sync with RN.
