www/py-django-taggit: Update to 1.1.0

Changes since 0.23.0:

• Added Finnish translation.
• Updated Chinese translation.
• Updated Esperanto translation.
• Fix form.changed_data to allow early access for a tags defined with blank=True.
• Backwards incompatible: Remove support for Python 2.
• Added has_changed() method to taggit.forms.TagField.
• Added multi-column unique constraint to model TaggedItem on fields content_type, object_id, and tag. Databases that contain duplicates will need to add a data migration to resolve these duplicates.
• Fixed TaggableManager.most_common() to always evaluate lazily. Allows placing a .most_common() query at the top level of a module.
• Fixed setting the related_name on a tags manager that exists on a model named Name.
• The project has moved to Jazzband. This is the first release under the new organization.
• Added support for Django 2.2.
• Fixed a race condition in TaggableManager.
• Removed method ItemBase.bulk_lookup_kwargs().
• Fixed view tagged_object_list to set queryset.model as ListView.model (was previously set as a ContentType instance).
• _TaggableManager and TaggableManager now always call the parent class init.
• Removed TaggableRel and replaced uses with ManyToManyRel.
