Empty directory created "preprocessed/YourDataSet" when training FP model

### Bug description

An empty directory will be created when training a FP model. `preprocessed/YourDataSet` with this message below printed in the logs.

`2025-04-23 09:55:15.736 | INFO | everyvoice.config.validation_helpers:directory_path_must_exist:89 - Directory at preprocessed/YourDataSet does not exist. Creating...`

This does not happen when training a vocoder.

### How to reproduce the bug

Normal FP training ...

`everyvoice train text-to-spec --devices 1 --nodes 1 config/everyvoice-text-to-spec.yaml`

### Error messages and logs

`2025-04-23 09:55:15.736 | INFO | everyvoice.config.validation_helpers:directory_path_must_exist:89 - Directory at preprocessed/YourDataSet does not exist. Creating...`

### More info

Comment from Sam ;-)

This is a haunting feature of pydantic

Start with the everyvoice.config.validation_helpers:directory_path_must_exist log location and the config/everyvoice-text-to-spec.yaml entry point, then reproduce the issue with the provided everyvoice train text-to-spec command. Done means normal FP training no longer creates the empty preprocessed/YourDataSet directory or logs its creation, while vocoder training remains unaffected.

Written by the indexing model from the issue text.
