This is a machine-generated codemod, but it's pretty safe since it was
generated by hooking into eslint's own report.
A few files had to be touched up by hand because there were existing
formatting issues with nested arrays/objects:
src/shared/utils/__tests__/OrderedMap-test.js
src/shared/utils/__tests__/Transaction-test.js
src/shared/utils/__tests__/traverseAllChildren-test.js
src/isomorphic/children/__tests__/ReactChildren-test.js
The intention of the `npm-react/**/*` rule was to copy recursively but it would have flattened any nested directory structure. I changed the `build/modules` rule to copy recursively as well, which is necessary for `ReactTestUtils` to be able to require `test/mock-modules.js` successfully. (`ReactTestUtils` isn't included in a clean `npm-react` build currently but it will be in the future.)
This also makes running ART tests more practical.
