[issue17802] html.HTMLParser raises UnboundLocalError:

Thanks for the patch Thomas!
Starting from your work I made an updated patch that fixes the bug, but at the same time the tests revealed another possible issue.
In case of invalid character references, HTMLParser still calls handle_entityref instead of reporting them as 'data'.  Not sure what the preferable behavior should be though, but anyway this is a separate issue.
