Something in Steam remembers about folders that already set up. Deleting the entry form libraryfolders.vdf doesn't work. Deleting steam.dll in the folder doesn't work. Deleting steamapps doesn't work.
The only consistent method I've found so far is to delete the entire library folder. Which is not ideal. Steam has a way of removing a library folder without deleting the literal folder. Figuring out how to do that would be ideal.
