Fixed a bug where the `pipeline.framework` would actually contain (#10970)

a fully qualified model.

We simply forgot to change the call for this one when this landed:
https://github.com/huggingface/transformers/pull/10888

It's odd that tests didn't catch that. Should we add some ?
(It's a pretty edgy test case, but it does run within the API).
