Including `eslint-plugin-import` cause lint postpone

When including eslint-plugin-import (even without any rules) cause tests to “stuck” after showing lint results.

Lint shows results, and then waits for some time before shell receives exit code.

Installed eslint dependencies:

Reduced eslint config

{
    plugins: [
        'react',
        'react-hooks',
        'jsx-a11y',
        // 'import'
    ],
    parser: '@babel/eslint-parser',
    parserOptions: {
        ecmaVersion: 10,
        sourceType: 'module',
        impliedStrict: true,
        ecmaFeatures: {
            jsx: true
        }
    },
    env: {
        browser: true,
        amd: true,
        es6: true
    },
    'extends': [
        'eslint:recommended',
        'plugin:react/recommended',
        'plugin:jsx-a11y/recommended'
    ],
    settings: {
        'import/resolver': {
            webpack: {
                config: path.resolve(__dirname, 'app/webpack.config.js')
            }
        },
    }
}

When un-commenting import line, i see this strange behaviour, like something happens in background after lint finished.

✖ 23 problems (6 errors, 17 warnings)
  3 errors and 4 warnings potentially fixable with the `--fix` option.

Sure, a PR to do so would be appreciated.

That should be added to readme, to avoid further mistakes.
