pass tests in ReactFinalForm.test.js
DO NOT MERGE without reading. This PR updates react to the new rc, and uses the new async act to silence a warning in ReactFinalForm.test.js Further, regarding Field.test.js, I rewrote `sleep` with `act`, and discovered some issues, and disabled some tests - 'should use isEqual to calculate dirty/pristine': This test goes into an infinite loop; it appears act() has caught an actual bug here. 'should `formatOnBlur` most updated value' and 'should pass multiple through to custom components' appear to be breaking some assumptions for react-dom, and should probably be fixed. I've included the warning messages that show for these warnings too.
