Michał Pierzchała dc25f209d7 chore: update Jest preset to align with Jest 24 (#24062)
Summary:
Jest 24 includes [`testMatch` and `moduleFileExtensions`](c5fd7aae93/packages/jest-config/src/Defaults.ts (L70)) that align with the ones that are currently there on master, because it added default handling for TypeScript as well. I think it's time for us to move to Jest 24. Is there a way we can tell users to upgrade Jest to certain version?

Fixes https://github.com/facebook/react-native/issues/24060
