eslint crash because of react/no-adjacent-inline-elements

[CleyFaye]

Versions:

• eslint-plugin-react: 7.18.3
• eslint: 6.8.0
• react: 16.12.0

When enabling the rule "react/no-adjacent-inline-elements", the following code causes eslint to crash:

React.createElement(a, b);

Minimal .eslintrc.js that trigger the issue:

module.exports = {
  plugins: ["react"],
  rules: {"react/no-adjacent-inline-elements": ["warn"]},
};

(setting react version does not change the issue)

Output:

$ npx eslint index.js 
Cannot read property 'elements' of undefined
Occurred while linting …/index.js:1

Expected:
Not crashing eslint, even if something's wrong with the code :)

Ouch, definitely a bug (altho i have no idea how you'd run into this)
