removing a project can break any future usage of nimble because of a nimble link.
While working on a nimble project removed a directory containing a different nimble project and now after making a new one and trying to run nimble install I get `The .nimble-link file is pointing to a missing file: /home/<username>/projects/nim-app/lua/lua.nimble`

This was fixed by removing a nimble-link file in  `.nimble/pkgs/lua-#head
