Good question.  We don't explicitly need to return `self` in this method if `repo` is returned is `RepoSynchronization#find_or_create_repo_with`.  I've made this update.  The only question I  have about not returning `self` is that the return value of `update_changed_attributes` will be different depending on if the conditional (`if full_github_name != new_full_github_name`) is true or not. Is it any clearer to return self?
