Integration Tests fail to import custom modules

Bug report

Describe the bug

Pre-configured integration tests from npx create-medusa do not work when registering a local module.

When I registered a local "auction" module, integration tests started failing with this error:

 FAIL  integration-tests/http/health.spec.ts
    Ping
      ✕ ping the server health endpoint (30 ms)

  ●  › Ping › ping the server health endpoint

    Cannot find module '/Users/derekwene/src/uplabs/lambda/apps/medusa2/dist/modules/auction'
    Require stack:
    - /Users/derekwene/src/uplabs/lambda/apps/medusa2/noop.js

      at resolveFileName (../../node_modules/resolve-from/index.js:29:39)
      at resolveFrom (../../node_modules/resolve-from/index.js:43:9)
      at Object.<anonymous>.module.exports (../../node_modules/resolve-from/index.js:46:47)
      at Object.<anonymous>.module.exports (../../node_modules/resolve-cwd/index.js:4:30)
      at getInternalModuleResolution (node_modules/@medusajs/modules-sdk/src/loaders/register-modules.ts:157:37)

I believe the issue is with this file:

https://github.com/medusajs/medusa/blob/develop/packages/core/utils/src/common/normalize-import-path-with-source.ts#L19

Since Jest is running these tests without ts-node it's incorrectly using dist instead of src.

System information

Medusa version (including plugins): 2 RC latest
Node.js version: 20
Database: Postgres
Operating system: OSX
Browser (if relevant):

Steps to reproduce the behavior

Run npx create-medusa-app@rc
Setup a custom module of any kind.
Try to run npm test:integration:http

Notice you get an error about failing to import module under ${CWD}/dist/${modulePath}

Expected behavior

Integration tests should pass.
