Upserted items are not bridged

When inserting or updating an item, the item is returned, but this item is not bridged, meaning that if the item was published and it's being updated some of the properties returned by the server are wrong.
The following properties:
```
in_catalyst: false,
is_approved: false,
is_published: false,
total_supply: 0,
```
are always set as fixed values, but that's not true if an items is being updated after being published.
