Update eslint-plugin-react

[efueger]

Description

Repo using eslint-4 channel and erroring with:

/usr/local/node_modules/eslint-plugin-react/lib/rules/no-unused-prop-types.js:663
            properties = node.params[1].properties;
                                       ^

TypeError: Cannot read property 'properties' of undefined
    at markPropTypesAsUsed (/usr/local/node_modules/eslint-plugin-react/lib/rules/no-unused-prop-types.js:663:40)

---

I think this might be related to a versioning difference with eslint-plugin-react:

• our eslint-4 channel is compatible with v7.7.0,
• and it looks like there was a change in support for no-unused-prop-types in v7.8.0.

---

Repo's config files:

• eslint config for GH issue.txt
• devDependencies for GH issue.txt

There is so many variations to these eslint plugins I get confused.
We have eslint-config-react-app might that be enough?

Disregard my confusion. The eslint-plugin-react was upgraded here: #459
