Prior to PR #36033, unexpected exceptions (e.g., ModuleNotFoundError) during hub model loading were not swallowed silently. They either matched specific except blocks or were raised.

After #36033, a catch-all except Exception block was introduced without a fallback else, causing unknown errors to be silently ignored and leading to misleading downstream behavior.

This commit adds an `else: raise e` to ensure only explicitly handled exceptions are suppressed. All others are surfaced, restoring pre-4.50 behavior and aiding in debugging and dependency visibility.

Since Transformers 4.51, the `.from_pretrained` method includes model
prefixes when reporting missing parameters. Following PR [1], this
commit aligns the `test_model_weights_reload_no_missing_tied_weights`
test to account for the new prefix behaviour.
