Fixes #1798 (closed)
Changed packages/react-scripts/scripts/init.js to suggest yarn build instead of yarn run build.

Trial run of the npm run create-react-app script screenshot: 
I'll also note that the commit message for 9d080d3e is incorrect; it should read "remove 'run' from 'yarn eject' command as well".
