Subject: [PATCH] tests: prevent assert_output_contains from aborting on no
 match

Bats runs tests under `set -eo pipefail`, so when `grep -F -o` finds nothing inside the count pipe it exits 1, the whole pipe fails, errexit fires, and the function aborts before reaching the count comparison. Wrap grep in `{ ... || true; }` so the pipe stays zero when the pattern is absent and the helper falls through to the flunk message.
