lb4 relation doesn't find models

Describe the bug

I have a project with a lot of models. I organized the models in "sub directories" inside "models" directory.
The "export" is working properly and all the project is working.
What is not working is the possibility to add repositories, relations or anything else
"lb4 relation" stops with an error "Generation is aborted: Error: No models found in ".../src/models"."
I expect the script to be capable to look for models also inside according to what is available in "index.ts" from "models" directory.

Reproduction

https://github.com/danysz/demo-lb4-cli-model-not-found

Inizia con il comando lb4 relation e il progetto di riproduzione collegato nell’issue, quindi esamina come analizza src/models e utilizza l’index.ts di quella directory. Il lavoro è completato quando i modelli organizzati in sottodirectory vengono rilevati per la generazione di relazioni o repository invece di produrre “No models found.”
