ACPT-1186
Using decorator for ObjectManagerFactory in order to better track objects created. In Collector, check if object's service name in sharedInstances of ObjectManager to compare it in skip list. In Comparator, Skipping objects that were previously skipped by Collector. Removed some dead code in Comparator. In Comparator, fixed bug with order of arguments to checkValues. Call _resetState on shared objects before and after each GraphQL request to make results more realistic. Needed to add more classes to state-skip-list.php .
