Issue loading absolute paths when not using baseUrl

[taeemo]

There's an issue with properly loading absolute paths.

Basically, we have a root tsconfig base:

{
  "compilerOptions": {
    ...
    "paths": {
      "entities/*": ["./app/entities/*"],
    }
  },
  "ts-node": {
    "require": ["tsconfig-paths/register"]
  }
}

Then we have another part of the app that tries to use that configuration but instead of fails:

C:\src\sample-paths\app\function> npm run start

> [email protected] start
> ts-node index.ts

Error: Cannot find module 'entities/SimpleClass'
Require stack:
- C:\src\sample-paths\app\function\index.ts

This works if I either set baseUrl: "." in the root tsconfig, or duplicate the paths inside the inner tsconfig.json

I've created a very simple reproducible repository here https://github.com/taeemo/ts-paths-issue

I've checked a bunch of tickets from this repo, this one seems similar #190 but not super sure.
