We fail to guess a sensible directory name for a newly cloned
repository when the path component of the URL is empty. E.g.
cloning a repository 'ssh://user:passw...@example.com/' we create
a directory 'passw...@example.com' for the clone.
Fix this by using parse_connect_url to split host and path
components and explicitly checking whether we need to fall back
to the hostname for guessing a directory name.
