Fix very old log params of log type rights for new api logparam style

After I9109a27f416b002e5c562a1454d8c373dcf98fb4 list=logevents also
called the log formatter for empty params, which than result in a
undefined index warning, because log entry without log params can exists
for the rights log type.
