Resolves #31167. https://github.com/go-gitea/gitea/pull/30885 changed the behavior of `repo.AvatarLink()` where it can now take the empty string and append it to the app data URL. This does not point to a valid avatar image URL, and, as the issue mentions, previous Gitea versions returned the empty string. --------- Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
