can't find React on app test, maybe because of hoisting

[sibelius]

Configuration error:
    
    Could not locate module React mapped as:
    /Users/sibelius/Dev/entria/app/entria-fullstack/packages/app/node_modules/react.
    
    Please check your configuration for these entries:
    {
      "moduleNameMapper": {
        "/^React$/": "/Users/sibelius/Dev/entria/app/entria-fullstack/packages/app/node_modules/react"
      },
      "resolver": null
    }

Why was this line commented out?

[sibelius]

this happens when I do something like this

cd packages/app
jest

running jest from root does not work either

check this: jestjs/jest#7359

[sibelius]

fixed here #18
