Error when linting CSS string with cache enabled.

[olegskl]

Describe the issue. Is it a bug or a feature request (new rule, new option, etc.)?

An error is thrown when trying to lint a CSS string while cache option is set to true.

Which rule, if any, is this issue related to?

Not applicable.

What CSS is needed to reproduce this issue?

Any CSS string.

What stylelint configuration is needed to reproduce this issue?

{
  "code": ".foo {}",
  "codeFilename": "foo.css",
  "cache": true
}

Which version of stylelint are you using?

7.10.1

How are you running stylelint: CLI, PostCSS plugin, Node API?

const stylelint = require('stylelint');

stylelint.lint({
  code: '.foo {}',
  codeFilename: 'foo.css',
  cache: true,
  config: {rules: []}
}).catch(console.error);

Does your issue relate to non-standard syntax (e.g. SCSS, nesting, etc.)?

No.

What did you expect to happen?

Lint should work. Not sure about caching (probably should be ignored?).

What actually happened (e.g. what warnings or errors you are getting)?

TypeError: Cannot read property 'reconcile' of undefined
    at prepareReturnValue (...\node_modules\stylelint\lib\standalone.js:174:16)
    at stylelint._lintSource.then.catch.then.stylelintResult (...\node_modules\stylelint\
lib\standalone.js:90:14)
