Deleting in-use cell type is no longer correctly prevented (in macroscopic)

[hhyyrylainen]

Due to the MP refactoring with the facade types the checks for deleting an in-use cell type is no longer working in either multicell or macroscopic. And it needs to be fixed in both.

Old analysis which may not be correct

I think this just needs looking up the edit facade instance for the cell type and then using that in the "is used" check to fix this bug so I'm tagging this as easy.

This is apparently fully working in the multicellular editor right now.

I can indeed reproduce the issue. I'd like to work on this then!

Wait, nevermind (kinda). The multicellular editor prevents me from deleting the types like it should, but macroscopic doesn't.

I haven't looked at this issue again recently but I think you may have done it in a way that didn't trigger the more advanced problem:
