Upgrade sane and use FSEventsWatcher on Darwin

[amasad]

This is to fix regressions with the NodeWatcher on macOS.
More info here: amasad/sane#97

Test plan

1. yarn test
2. on macOS create a new dir and install a preposterous number of node_modules
3. run jest tests in that directory using this branch

Shouldn't this be https://github.com/facebook/jest/blob/master/packages/jest-haste-map/package.json#L15?

[cpojer]

yes!

[cpojer]

Anybody wants to send a fix for this so we can get it into the next Jest release?

[SimenB]

Ask and you shall receive: #3918

[amasad]

Thanks! I sent this on go so couldn't update. Feel free to close this one.

[kirkstrobeck]

Anybody know when the next Jest version will be released with this fix?
