Look past voice lookups that found nothing

A motion queued behind a voice fly-to acts on the last flight that moved the camera. A later lookup that was not found, threw, or was cancelled once a newer voice fly-to had begun moved nothing, so the motion looks past it rather than refusing or running early and cancelling the flight still in the air. It never acts at a flight older than the one it started waiting on. A lookup cancelled while still the latest voice flight (a search, a share link, Cockpit) still refuses.

The top-down no-op now reports the camera's real pitch.
