tst_selftests falsely claims its blacklisted sub-test crashes

Commit 28da6a103f032ed8913ee978d012613a33ac900d removed the part of the test that actually did crash, but neglected to correct meta-data in tst_selftests.cpp and the generated_expected_output.py script that continues claiming it does crash. So this is handled as a crashing test when it, in fact, is not.

Naively removing it from the various lists of crashing tests triggers Catch2 to report failure of the selftest, blaming all the other crashing tests, when nothing about them has changed.
So this shall require someone who can make sense of what Catch2 is doing, to fix it.
