Since Google is now pointing towards this post, here's the answer:
As explained by unity in this post:
https://blogs.unity3d.com/2018/06/20/introducing-new-prefab-workflows/
You need to use "unpack Prefab" in the right click menu, to unlink the prefab before deleting the prefab in the project view.
