Relay compiler --watch and yarn start

[quolpr]

It is a little bit strange, that I need to run yarn relay on each iteration or run the watch process in another tab. So, I made such start command:

node ./setup && concurrently \"PORT=4000 react-scripts start\" \"relay-compiler --src ./src --schema ./src/schema.graphql --watch\"

Is this a good way? And should I create PR?
