When clone fails, only remove directories we have created (not other directories)

Dependencies

• [2] B3QWIGDE Fixing the Git features with the latest Pijul (+ conflicts in Cargo.toml)
• [3] RGJWLQWB When cloning, try to init *before* setting up the path Drop (pijul::commands::clone::RepoPath)
• [4] SXEYMYF7 Fixing the bad changes in history (unfortunately, by rebooting).
• [5] LYTVEPH3 Avoid cloning into an existing path
