evolve: ui.progress doesn't use total count if pos is None, let's drop it Every other call of ui.progress that has argument #2 (named `pos`) set to None doesn't specify `total`, because it won't be used. Basically, ui.progress(action, None) is enough, when used like this it hides progress bar because the action is considered completed. So this is just a minor cleanup patch.
