…ar out the object/Synchronized block cache. Added an end iteration callback registration to the TestingEngine constructor that will clear out the Monitor.SynchronizedBlock cache after each iteration to be sure no entries carry over across iterations for cases such as the max step bound being hit and all controlled operations being abruptly stopped.

When an iteration is stopped due to the maximum step bound being hit, all the controlled threads/operations are abruptly interrupted which can leave orphaned entries in the Monitor.SynchronizedBlock.Cache. When subsequent iterations try to run, they are all guaranteed to fail quickly because they will find instances of SynchronizedBlock in the cache from the previous runtime.
This fix is to make sure the cache is cleared after each iteration run.
