test(trash): update model-count assertions after Event removal

restore() / purge_expired() now iterate 6 soft-deletable models (Note,
Project, Milestone, Rulebook, RulebookTopic, Rule) — Event was removed
with the calendar surface. Adjust the two count-coupled assertions
(execute.await_count 7→6; the rowcount list drops a zero so the sum
stays 4). Caught by CI run #2580.
