test: collect timeout signals explicitly

Force collection on a later turn while the timeout sources are only
retained by AbortSignal.any(). Shorten the first timeout and clear the
watchdog after the assertion. This preserves the source-retention
regression check without waiting ten seconds on successful runs.
