Cached objects are troublesome for object graph traversal

[abeham]

If there are objects in the cache they may prevent object graph traversal from completing successfully.

r13494 Excluded all Types from System.Reflection.Emit from object graph traversal.

The problem occured during object-graph traversal, where GetObjectGraphObjects accesses the GoogleProtoBuff-Message in the CacheEntry. Accessing some of their members causes Reflection.Emit to create code that throws an exception.

When calling GetObjectGraphObjects, some types are already excluded from being returned, like the SignatureHelper from Reflection.Emit (due to simmilar problems). To fix problems with Reflection.Emit types, all types from "System.Reflection.Emit" are excluded now.

r13510 Fixed wrong excluding of types in object graph traversal (no members were traversed any more). Added a unit test that verifies that GetObjectGraphObjects yields a reasonable number of objects.

Reviewed r13494 and r13510.

Please change the unit test name to a more descriptive one.
