Fix broken CLIP position IDs in SDXL model doesn't work

When trying to fix an SDXL model with broken `embeddings.position_ids` like https://civitai.com/models/133005/juggernaut-xl version 5, I get:

```
Model is 6.46 GB. Model type identified as VAE-v1-BROKEN. Model components are: VAE-v1-SD.
Contains 6.31 GB of junk data!
Model will be pruned to 159.56 MB.
```
