Summary:
Fixes broken ios/android e2e tests for CI.
Changes:
1. Use `npm pack` instead of `yarn pack` during e2e test
2. Update test string assertions in ios/android e2e tests
3. Use `Step One` as candidate for source code replacement to test for page changes (since the "Welcome to React Native" string exists in the `Header` component instead of being on `App.js`)

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.
