helper fails before it gets a chance to ask me for password

[yacoob]

I'm trying to git clone a repository that stores images on Netlify's LFS. With helper set up, I get:

Username for 'https://39fb5576-3cb9-4a94-b61c-4e9eb0fd9108.netlify.com': _

I'm not logged in, so there's no config file to read the credentials from. However, the helper fails after discovering that, instead of asking me for the login and password. The subsequent prompt for username comes from git itself.

My go-fu is pretty poor, but it looks to me like the problem lies in getAccessToken. It calls loadAccessToken which tries four different files (validAuthPaths) and fails to find any of them. As a result, it returns the last error it has noted ("open /home/yacoob/.config/netlify.json: no such file or directory") at l.148 and exits getAccessToken, before it can get to l.157 which would ask for the credentials.

The asking for credentials is broken as well, according to this bug but that's a separate problem :D
