SMA-10 round 3: Start clears a failed hand-back streak; the hook is tested

When control takes the unit again, release_fails, release_retry_at and
release_zero_sent are reset, so the next Stop is a new streak with its own one
0 W, error line and event. Tests: a streak that Start interrupts without a
recovery; a driver that overrides release_fallback(). _BACK_NL "de eigen
sturing" (round 2) is kept.
