Change conference name from multi-lingual field to CharField

- Convert Conference.name from I18nCharField to models.CharField
- Remove unused I18nCharField import from conference model
- Create migration 0055 to handle database schema change
- Update GraphQL Conference type to use regular field instead of localized resolver

Fixes #4066
