Fixing "SyntaxError: Unexpected token export"

[arichter83]

I had this error:

    Details:

    /Users/ar/meteor-react-typescript-nightwatch/node_modules/meteor-jest-stubs/lib/meteor/react-meteor-data.js:3
    export const withTracker = jest.fn(Op => jest.fn(C => createContainer(Op, C)));
    ^^^^^^

    SyntaxError: Unexpected token export

And could fix it with inlcuding this module again for the transform:

  // An array of regexp pattern strings that are matched against all source file paths, matched files will skip transformation
  transformIgnorePatterns: [
    "<roodDir>/node_modules/meteor-jest-stubs"
  ],

If this is always the case, it should be included in the README.
