nest: [9.x.x] Duplicate Provider names don't get shown in REPL-debug() function

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

Given the following Diagram:

graph TD;
  AppModule((AppModule))-->CatModule((CatModule))
  AppModule-->AppService_A>AppService]
  AppModule-->foo_A>provide: 'Foo', useValue: 'bar']

  CatModule-->AppService_B>AppService]
  CatModule-->foo_B>provide: 'Foo', useValue: 'barbaz']
  CatModule-->CatService>CatService]

Both the AppModule and CatModule have providers with the same name but different implementations/instances. When using the NestJS repl() method and print a debug() statement in order to list the application context, the AppService & Foo provider does not get listed within the CatModule.

[Nest] 5340  - 07/08/2022, 11:18:42 AM     LOG [InstanceLoader] CatModule dependencies initialized
[Nest] 5340  - 07/08/2022, 11:18:42 AM     LOG [InstanceLoader] AppModule dependencies initialized
[Nest] 5340  - 07/08/2022, 11:18:42 AM     LOG REPL initialized
> debug()

AppModule:
 - controllers:
  ◻ AppController
 - providers:
  ◻ AppService
  ◻ Foo
CatModule:
 - providers:
  ◻ CatService

Minimum reproduction code

https://github.com/BrunnerLivio/nestjs-repro-duplicate-provider-repl

Steps to reproduce

1. npm ci
2. npm run start:dev
3. Write debug() within REPL console

Expected behavior

Should list all providers

[Nest] 5340  - 07/08/2022, 11:18:42 AM     LOG [InstanceLoader] CatModule dependencies initialized

[Nest] 5340  - 07/08/2022, 11:18:42 AM     LOG REPL initialized
$ debug()

AppModule:
 - controllers:
  ◻ AppController
 - providers:
  ◻ AppService
  ◻ Foo
CatModule:
 - providers:
  ◻ CatService
