npm auth bug in yarn run

Scripts run with yarn run seem to break npm auth.

Tested on:

• macOS 10.12.6
• node v8.11.0
• npm v5.8.0
• yarn v1.6.0

repro

1. Delete or move .yarnrc
2. yarn cache clean
3. Ensure .npmrc is set up properly with an authToken
4. npm whoami works
5. npm run who works
6. yarn run who fails with ENEEDAUTH

workaround

1. yarn config set registry https://registry.npmjs.org
2. yarn run who works

package.json

{
  "name": "yarn-run-whoami",
  "version": "1.0.0",
  "main": "index.js",
  "license": "MIT",
  "scripts": {
    "who": "npm whoami"
  }
