The checker stopped reading a level's test results at the first that did not pass and kept only its first failure, so a check named one fault per round. It now reads and counts every result and writes every failed test with its first line into the verdict's Failures and the try's failed list (at most 50, then how many more); Failed keeps the first one's words whole (issue 1901). Pins mesh-sdk fix/1921-every-failure.
