Describe the Bug

When doing a POST to create a new item in a collection, the response is a completely different item.

I am using Axios to send the request from a React application.

1. This is the payload I sent to the API

2. This is the response

Judging by the property deck_name we see it's a completely different item. However, the newly created item is correctly created in the database and the correct relations are there. So it's just the response that's wrong.

To Reproduce

1. Have a collection with some items in them
2. Create a new item using POST via the API
3. Log the request response
4. See a different item is returned instead of the newly created one
