Improve robustness on temporary connection issues to the Hugging Face Hub

When the model is loaded from its name like WhisperModel("large-v2"), a request is made to the Hugging Face Hub to check if some files should be downloaded.

It can happen that this request raises an exception: the Hugging Face Hub is down, the internet is temporarily disconnected, etc. These types of exception are now catched and the library will try to directly load the model from the local cache if it exists.
