chore(minipipeline): add test case for ooni/probe#2456 (#1461)

This commit adds a test case that replicates the issue described by
ooni/probe#2456 and shows that we are now able
to correctly deal with that. Check the `analysis.json` and
`analysis_classic.json` file and see that there are no unexplained or
unexpected TCP connect failures. This happen because now we filter for
IPv6-related failures.
