[PATCH 2/2] urlmon: If ProtocolCF_CreateInstance doesn't support aggregation retry without it.

[Jacek Caban]

Hi Dmitry,

Those changes look mostly good, but we should probably not forward QI 
calls in BindProtocol_QueryInterface if the protocol doesn't support 
aggregation.

Also I don't mind tests from patch 1, but it would be probably easier to 
extend test_CreateBinding(). It would also make a testing the above 
comment trivial.

Thanks,
Jacek
