Added tests to check the release of ownership of objects returned from Python.
The ObjectModel test class was introduced to check if the transference of ownership of objects returned from Python to C++ through a virtual method is working properly. Also updated the other test that uses the ObjectView class. Reviewed by Lauro Moura <lauro.neto@openbossa.org> Reviewed by Luciano Wolf <luciano.wolf@openbossa.org>
