Title: Add front publication to SupportingItems

`SupportingItems` loose their `frontPublicationDate` if they had one from being at the root level of a `collection`.

This will carry it on if it already has one, and if not will just exist without one. This also stops the fact that putting an item into supporting would clear `frontPublicationDate`.
