closes https://github.com/TryGhost/Team/issues/3170 - When resources that are related to automatic collection filter are updated the posts in collections should be updated as well. - This change adds a super-basic way to track changes in post/tag/author resources and updated all automatic collections when any of those resources change. In the future we can optimize the update process to be more performant, but it's good enough for current needs
