testament :show duration also for failed tests; improve `tshould_not_work`; mitigate #17946 tchannels timeouts (#17947)

* refs #17946; refactor testament test summary, show test duration for failures; increase timeout tchannels

* revert workarounds from https://github.com/nim-lang/Nim/pull/16698 and add allowPrefixMatch optional param to greedyOrderedSubsetLines

* add test

* workaround for yet another testament bug
