[issue19005] PyIter_Next crashes if passed a non-iterator

[Evgeny Kapun]

New submission from Evgeny Kapun:

According to the documentation, PyIter_Next should raise TypeError if passed an object which is not an iterator as an argument. Instead, it calls a function through a null pointer, which leads to a crash.
