tests: fix invalid C++11 code

* tests/c++.at (Object): Somehow instances of Object were assigned
YY_NULL, which is 0 most of the time (that case passes), but is
nullptr in C++11, and there is nothing in Object to support such an
assignment (failure).  Use 0 as value, and provide the needed
assignment operator.
Also, use a more natural order within the class definition.
