AutoObjectCmd.exe test with required lib

IDispatch.Invoke cause 80020005 error on out IUnknown param, when call argument
is IDispatch. Sounds like right result, but Windows try to cast out parameter
to argument type. Attached application with library should fail in Wine on such
call - simple run AutoObjectCmd.exe.

Confirming and clarifying title. We actually have a bunch of tests in
oleaut32:tmarshal that are currently marked TODO because of this.
