SetProject() doesn't work after v2.3.1 update

[opennoise1]

What is the current behavior? I have a script that, on Start(), sets my dialogue runner's Yarn Project. It chooses a Yarn Project from a list of them, and then calls SetProject(). This script always worked, but it suddenly stopped setting the project after I updated to Yarn Spinner v2.3.1. Even though SetProject() is called, dialogue.YarnProject remains null.

Please provide the steps to reproduce, and if possible a minimal demo of the problem:

1. Create a new scene.
2. Add the Dialogue System prefab that comes with Yarn Spinner into the hierarchy.
3. Create a scene manager object in the hierarchy.
4. Write a script that creates a list of projects and calls SetProject() on Start(). Something like this:

   
   using System.Collections;
   using System.Collections.Generic;
   using UnityEngine;
   using Yarn.Unity;

public class TestForYarn : MonoBehaviour { public DialogueRunner dialogue; public List yarnProjects;

// Start is called before the first frame update
void Start()
{
    dialogue.SetProject(yarnProjects[0]);
}

}

5. Attach that script to the scene manager object.
6. Add a Yarn Project into the `yarnProjects` list on the script in the inspector.
7. Make sure to reference the Dialogue System's dialogue runner on this script in the inspector too.
8. Press play.

**What is the expected behavior?**
I expect the correct Yarn Project to be assigned to the dialogue runner.

**Please tell us about your environment:**

  - Yarn Spinner Version: 2.3.1
  - Unity Version: 2021.3.27f1

**I've attached a few screenshots of how everything should be set up:**

this should have been closed when #246 was merged, my bad.
