Shall we use GCController.collectAll()?

I've repeatedly tested, and didn't see a need for it.

 var initialize_SearchTest = function() {
-
 InspectorTest.dumpSearchResults = function(searchResults)
 {
     function comparator(a, b)
     {
         a.url.localeCompare(b.url);
     }
     searchResults.sort(comparator);
 
     InspectorTest.addResult("Search results: ");
     for (var i = 0; i < searchResults.length; i++)
