Issue #29507: Update test_exceptions test_unraisable() of test_exceptions expects that PyErr_WriteUnraisable(method) fails on repr(method). Before the previous change (7b8df4a5d81d), slot_tp_finalize() called PyErr_WriteUnraisable() with a PyMethodObject. In this case, repr(method) calls repr(self) which is BrokenRepr.__repr__() and the calls raises a new exception. After the previous change, slot_tp_finalize() uses an unbound method: repr() is called on a regular __del__() method which doesn't call repr(self). repr() doesn't fail anymore. PyErr_WriteUnraisable() doesn't call __repr__() anymore, so remove BrokenRepr unit test. [#29507]
