haus hangs cloning repo if authentication with git repo fails

Rather than failing, haus hangs trying to clone a repo if authentication with the repo fails.

Apparently this isn't a bug, but a feature in git2go

libgit2/git2go#246

The remote callback for fetch will loop on the CredentialsCallback until it succeeds ignoring failures. If the credentials callback can break the loop that would allow an error to be displayed. I'm Looking into seeing if I can figure out how to make that happen.
