Doesn't work with branches

I needed to download a directory that was missing from another branch to fix a build, tried cloneit... no love :cry: 
```
cloneit https://github.com/ActivityWatch/aw-tauri/tree/dev/update-deps/src-tauri/icons
[1/2] Cloning "https://github.com/ActivityWatch/aw-tauri/tree/dev/update-deps/src-tauri/icons"...
[1/3] 🔍 Validating url...
[2/3] 🚚 Downloading...
No commit found for the ref dev
```
