Exit a release that is already live instead of promoting again

Re-running a release whose sha is already live fell through to a fresh
promotion: a new target, a new build, and a roll of a fleet already serving
exactly what was asked for. Nothing to do is a valid outcome, and it has to be
decided before anything is promoted.
