Internal Dataloaders don't take `entity_path_prefix` into account

**Describe the bug**
`entity_path_prefix` does not seem to work on `rerun.log_file_from_path` on 0.20.3.


**To Reproduce**
```
rec = rr.new_recording("app", spawn=True)

rr.log_file_from_path(
    "cube.stl",
    entity_path_prefix="test",
    recording=rec.to_native(),
)

```
