Upgrading prettier from ~1.12.1 to ^1.13.6 causes eslint-plugin-html to break.
I add this issue here, because I think this violates semver.

Environments:

• Prettier Version: 1.13.6
• Running Prettier via: eslint-plugin-prettier
• Runtime: Node v10.5.0 Yarn 1.7.0 Npm 6.1.0
• Operating System: Windows
  eslint@^5.0.1
  eslint-plugin-html@^4.0.5
  eslint-plugin-prettier@^2.6.1
  prettier@^1.13.6

Steps to reproduce:
Add plugins html and prettier to .eslintrc
Add an html file to your project
Run eslint **/*.{js,html}

Expected behavior: (1.12.1)
yarn run v1.7.0
$ eslint **/*.{js,html}
Done in 5.89s.

Actual behavior: (1.13.6)
yarn run v1.7.0
$ eslint **/*.{js,html}
