Infrastructure: Temporarily comment out flaky tests (pull #1488)

Disable a few unreliable regression tests that we don't want to impede other work while we determine the root cause of the inconsistent test behavior.
This change comments out tests that fail most frequently in CI.
The regression test coverage report will report them as missing.
The work to resolve the root issue is tracked by issue #1415.
