Empty pkgs folder is created every time I run a nimble command
Since upgrading to nimble v0.12.0, everytime I run a nimble command, it create an empty `pkgs` folder in the current folder I'm in.

This is under Ubuntu 20.04 running on WSL2.

Important details : I added local dependencies by providing my own json file path in ~/.config/nimble/nimble.ini . Could it be related ?
