Returns a new item containing the same values as this item but no id.

Additionally, the item will be a variant child of this item.

NOTE: if this item is not a variant base itself, this item will return a item
that is a child of this items variant base. i.e. exact clone.

@return \MetaModels\IItem the new copy.
