## Description

### Steps to reproduce

1.  Be on an OpenProject instance with a large amount of projects, of which many are in a parent-child relation
    
2.  Call `/api/v3/projects`
    
3.  Watch the Active Record server logs
    

### What is the buggy behavior?

An N+1 query on the projects table is happening, slowing down the response.

### What is the expected behavior?

No N+1 query.
