avoid error on not finding path

[ferdymercury]

Use full repo name always, to avoid fatal: destination path 'directory/anotheruser/repo' already exists and is not an empty directory. when running gitim a second time on an already cloned repo from other user

Also, forward the username automatically to the clone url
