Reproduction

See https://github.com/andreaswolf/nuxt-issue-repro

Run yarn run vitest --project=e2e for a working test, yarn run vitest --project=e2e-nuxt will not work.

Describe the bug

Tests run fine without Nuxt/defineVitestProject. As soon as I use defineVitestProject(), there are two errors and the tests are not run anymore:

1. Error: Failed to import test file /home/aw/Kunden/fes/fes-cp-v11/frontend-v2/node_modules/@nuxt/test-utils/dist/runtime/browser-entry.mjs
   Caused by: SyntaxError: The requested module '/node_modules/qs/lib/index.js?v=c5ced9fb' does not provide an export named 'default'

2. TypeError: Cannot set properties of undefined (setting 'PROD')

The second issue (very likely) comes from setupEnv in vitest's setup-common.js. I can also open a separate issue for this.
