More fixes for issues introduced by rebasing

**what is the change?:**
- Remove some outdated 'require' statements that got orphaned in 'React.js'
- Change 'warning' to 'lowPriorityWarning' for 'React.createClass'
- Fix syntax issues in 'React-test'
- Use 'creatReactClass' instead of ES6 class in ReactART
- Update 'prop-type' dependency to use no higher than 15.7 because 15.8 limits the number of warnings, and this causes a test to fail.
- Fix some mixed-up and misnamed variables in `React.js`
- Rebase onto commit that updates deprecation messages
- Update a test based on new deprecation messages

**why make this change?:**
These were bugs introduced by rebasing and tests caught the regressions.

**test plan:**
`yarn test`

**issue:**
#9398
