[URP] NullReferenceException error is thrown on deleting Renderer Feature object in CustomForwardRendererData asset

Package: Scriptable Render Pipeline Universal


NullReferenceException error is thrown on deleting Renderer Feature object in CustomForwardRendererData asset after removing the object from its preset.

Note: Workaround is to first select a valid "Renderer Feature" for the item which shows "missing" and then remove the item.

Steps to repro:
1. Create a new project.
2. Windows > Package Manager > Universal RP > Install.
3. Project Window > Right Click > Create > Rendering.
4. Universal Render Pipeline > Forward Renderer > Add Renderer features.
5. Create its Preset > Delete Renderer Features.
6. Select "CustomForwardrendererData" asset.
7. Delete the missing object from Renderer Features list.

Actual Result:
NullReferenceException error is thrown in the console.

Expected Result:
No errors in the console.

Reproducible on:
2020.1.0a12, 2019.3.0b10, 2019.2.0f1, 2019.2.0b1 (with LWRP 6.7.1)

  1. Resolution Note (fix version 9.0.0-preview.1):

    Presets are disabled for the ForwardRenderer asset as they are not needed, also missing or empty entries can be removed if necessary without error now.
