closes https://github.com/TryGhost/Ghost/issues/12791 closes https://github.com/TryGhost/Team/issues/566 https://github.com/TryGhost/Ghost/pull/12787 introduced a significant performance regression due to a misunderstanding of when Bookshelf calls `.format()` ([related upstream issue](https://github.com/bookshelf/bookshelf/issues/668)). We expected `.format()` to only be called on save but it's also called when Bookshelf performs fetching and eager loading which happens frequently. `.format()` can be a heavy method as it needs to parse and serialize html and markdown so it should be performed as infrequently as possible. - override `sync()` in the base model so we can call our own `.formatOnWrite()` method to transform attributes on `update` and `insert` operations - this was the only feasible location in Bookshelf I could find that is low enough level to not require modifying model instance attributes - gives models the option to perform heavy transform operations only when writing to the database compared to the usual `.format()` method that is also called on fetch in many situations
