(RIN forum) added hotfix 3 by ce20fdf2 from https://cs.rin.ru/forum/viewtopic.php?p=2921215#p2921215

* + added missing implementation of (de)sanitize_string when NO_DISK_WRITE is defined which this fixes compilation of lobby_connect

* + check for empty string in (de)sanitize_file_name() before accessing its items
