[FIX] html_image_url_extractor: Do not test the specific exception

Newer versions of LXML raise different exceptions.

It doesn't matter, as long as there's an exception, so we move to less explicit tests.

Newer versions also parse more wrong XML as good HTML, so a test that was expecting a failure and now doesn't is removed.
