Simplify reconstruction test assertion

Replace `assert_event_journal_contains_at_least_ordered` helper with an
inline drain that just counts the gossip + reconstruction events. The
helper was carrying around `WORKER_FREED` bookkeeping and a strict
prefix-match for one caller; counting the two relevant work types until
both thresholds are met is the same check with much less code.
