refactor: Remove unused imports in load_toponyms.py

This commit removes an unused import statement in the `load_toponyms.py` file. The import for `django.core.exceptions.ObjectDoesNotExist` is no longer needed and can be safely removed.

This change improves code cleanliness and removes unnecessary dependencies.
