Change 2107b9c16d7be1292c5439a47ed31871906e0b1f implemented making base class functions visible via "using" directive. However, since it was implemented in getInheritedFunctions() based on names, it did not work for constructors since they have a different name. As a consequence, no tp_init function was generated for the test case and the tp_init function was called instead, creating a base class instance. Add a function that adds the base constructors for the simple case of the class having no constructor in case "using" was specified. Add a data member to the test to test this. [ChangeLog][Shiboken6] Making base class constructors visible via "using" directive has been fixed for simple cases.
