Bump to allow for React 16, fix test

[ockham]

Broken out of #11.

To test:

• rm -r node_modules/
• npm install
• grep version node_modules/react/package.json (should return 16.something)
• npm run test should pass

I followed the testing instructions and everything lgtm.
CircleCI is upset for reasons that I doubt are relevant to this PR:

Warning: Permanently added the RSA host key for IP address '192.30.253.112' to the list of known hosts.

Permission denied (publickey).

fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

git command i returned 128: 

I've opened an issue for it but feel free to 🚢 in the meantime

The package version you mean? Yeah, wasn't sure about immediately releasing vs trying to also get #11 in, but then again, let's not get blocked by that.
