MOCK_EXPECT(...).moves(...) fails to compile if return value is a unique_ptr

[Chris Ritchey]

The following code fails to compile with an error "cannot convert argument 1 from 'std::reference_wrapperstd::unique_ptr<Interface,std::default_delete<_Ty>>' to 'std::nullptr_t'"

could be a regression of http://sourceforge.net/p/turtle/tickets/15/ ?

class Mock : public virtual Interface

};
