pUnoReturn should be null when UNO methode is VOID
the problem is that at least the msvc_win32_x86-64 bridge's
unoInterfaceProxyDispatch
(bridges/source/cpp_uno/msvc_win32_x86-64/uno2cpp.cxx)
requires pUnoReturn to be a nullptr when the UNO method has VOID
return type (see computation of retKind in cpp_call in the same file),
but that IdlInterfaceMethodImpl::invoke doesn't set up the arguments
according to that expectation.
