Hi all,

could you please review this small and straightforward patch which converts TestVirtualSpaceNode_test into GTest? TestVirtualSpaceNode_test have been removed from executed by 8198423[1] and some of its asserts aren't true any more. I have them commented them out, and filed 8212932[2] to clean them up.
