maven: Update test that is now failing since beautifulsoup4 4.13

Latest beautifulsoup4 release (4.13) seems to have fixed issues
related to unexpected encodings in XML files so a test that was
passing previously is now failing.

Update that test to check origin URL and visit type can be
successfully extracted from a POM file with unexpected encoding.
