Looking at the code, it wasn't uploading contacts - rather it retrieved the favicons by looking on the domain in question, when a user turned that feature on manually. Some apps do upload user contacts - they take the whole list, and cart it off to their own server. The app doesn't seem to be sending anything to its own server - it's fetching something the user asked it to fetch.
