Ensure that Service Worker clients are always returned in MRU order (2)

This extra flag is kind of tricky, I'd just remove the sorting from this
function and let the caller deal with whether they want to sort it or not. It
looks like the only other test using this
clients-matchall-include-uncontrolled.html is already sorting the expected urls
so it's natural to also sort the actual urls.

       port.postMessage(message);
     });
 };
