feat(upgrade): Upgrade to react@16.7.0 (#13555)

This upgrades react to 16.7.0. This is the latest version before hooks. It looks like most changes in 16.8.x are related to hooks and since we currently do not have any plans surround hooks, lets just upgrade to 16.7 until we do.

Summary of changes:
- `React.memo()`
- `React.lazy()` for code splitting

See https://github.com/facebook/react/blob/master/CHANGELOG.md#1660-october-23-2018
