Conformance tests: Align automated and manual scoring #1692

In #1678 I added an automated tool for scoring the conformance test suite, and #1682 and #1683 added some features to support edge cases.

Now I am working on going through the remaining files where the automated conformance judgment on a file differs from the manual one (open PRs: #1684, #1685, #1687, #1688, #1689, #1690, #1691).

I'll use this issue to track the remaining discrepancies (from conformance/src/unexpected_fails.py):

Any help is appreciated.
