quartz/tests: Test aggregation with CLSID_FilterMapper2. 

MPC-HC v1.7.10's CFGManager class creates a filter graph object during
its constructor, which means it passes in an outer object with a zero
reference count. Wine does an AddRef/Release on this object when
constructing the filter graph, thus its reference count drops back
to 0 and the CFGManager object gets freed prematurely.
