Updating create-graphql breaks other projects
running `yarn global upgrade create-graphql` to update. Then running a project that was created with it and you get this. Seems odd because you would think that create-graphql gets out of the way after you have generated your file. If you rm -rf node modules, yarn install, it works. 

Any idea why its doing this?
