Creating a prefab in an empty directory

[nipunasudha]

A prefab cannot be created in a newly created empty directory. When I drag the gameobject into the directory, the directory is already gone, cleaned up by the empty dir remover.
Unity gives me an error saying dir not found.

I use Unity 2018.3.7f1

Apparently new Prefab system forces Save Assets event on prefab creation. Well, it makes sense :)
I made a fix for this in this commit
Thanks for the report
