Resolves #123: Generalize display name to include wards; dedupe juris…

Change Type

• YAML data change (divisions / jurisdictions)
• Code change

Summary

Division YAMLs for ward: OCDids are named without a ward designation or number — the ward number never enters display_name, so the filename collapses to just the place name and a UUID.

This change resolves that issue by handling the ward segment.

As well, moves derive_jurisdiction_ocdid functionality to jurisdiction_seed.py file -- we are duplicating some code there.
