[WIP] Fix Tortoise not populating nested models

[marcoaaguiar]

FastAPI-CrudRouter + Tortoise

Tortoise models can have 3 "types" of pydantic models:

• Regular pydantic models (BaseModel)
• Uninitiated Tortoise's pydantic models (PydanticModel)
• Initiated Tortoise's pydantic models (PydanticModel + Tortoise.init_models)

Tortoise initiated vs uninitiated models

Uninitiated models are models that are typically written in a module's body and are not preceded by a Tortoise.init_models(...).
Initiated models are aware of its related models (Foreign fields) and will include these fields in the created Pydantic models

Test cases:

The proposed test cases are the cross-product of the possible "types" of Pydantic model vs. having nested models or not.

Cases:

• No nested - Regular pydantic models (BaseModel)
• No nested - Uninitiated Tortoise's pydantic models (PydanticModel)
• No nested - Initiated Tortoise's pydantic models (PydanticModel + Tortoise.init_models)
• Nested - Regular pydantic models (BaseModel)
• Nested - Uninitiated Tortoise's pydantic models (PydanticModel)
• Nested - Initiated Tortoise's pydantic models (PydanticModel + Tortoise.init_models)
