[issue31455] ElementTree.XMLParser() mishandles exceptions

Right, Zachary, thanks for noticing. Py2.7 is actually way more different than I thought, and I hadn't paid enough attention to that. Py3 does all of this in "__init__", whereas Py2 essentially implements "__new__" in C, which requires more cleanup.

BTW, the implementation in Py3 would also benefit from refactoring the error handling code and moving it all in one place. But it shouldn't suffer from the same kind of problem, at least.
