Removes all references to the question in executed tests in case the question has been changed. If a question was changed it cannot be guaranteed that the content and the meaning of the question is the same as before. So we have to delete all already started or completed tests using that question. Therefore we have to delete all references to that question in tst_solutions and the tst_active entries which were created for the user and test in the tst_solutions entry.
