v0.128.0 introduced non-deterministic openapi spec schema naming in
the case of multiple pydantic models with the same name.
Commit [e300630](e300630551 (diff-1086603fdd56511aafd1d279396b142b803e48164327148e6de26cef4cdaed81L504))
removed the check for conflicting names.
The component names two classes named `User` would randomly be either
```
User
tests__test_duplicate_model_names_openapi__b__model__User
```
```
tests__test_duplicate_model_names_openapi__a__model__User
User
```
With this change, we reintroduce the conflict check to always use
fully qualified names in case of conflict.
