Some filters do not work with GraphQL board lists

This is something I found while working on #118742 (closed). With the graphql_board_lists feature enabled, filtering by None / Any assignee does not work.

The Assignee = None filter uses the assignee_id param so we should handle this similar to epicWildcardId.

This would also need some backend work to accept assigneeWildcardId in GraphQL.
