Bug: exports field is not respected when running under PnP

[merceyz]

Describe the bug

When running enhanced-resolve under Yarn PnP the exports field is not respected

To Reproduce

Setup:

mkdir repro && cd repro
yarn init -y
yarn set version berry
yarn add enhanced-resolve rollup

Code:

import { ResolverFactory, CachedInputFileSystem } from 'enhanced-resolve';
import fs from 'fs';

const cachedFS = new CachedInputFileSystem(fs);

const resolver = ResolverFactory.createResolver({
	fileSystem: cachedFS,
	conditionNames: ['node', 'import'],
});

resolver.resolve({}, __filename, 'rollup', {}, (err, filepath) => {
	console.log(filepath)
	// filepath ends with `rollup\dist\es\rollup.js` when running under node_modules
	// and `rollup\dist\rollup.js` when running under PnP
});
