short-circuit drop Team-related votes

This PR has the effect of subsetting the short-circuit vote to the elected+appointed members of the AB + TAG, which I believe is correct, as TimBL and the CEO (and other Team contacts if any) have likely already had the chance to contribute to the Team recommendation for the short-circuit.

This PR is based on discussion in #793, and generalized beyond just TimBL.

If we accept this PR then we can close #793 without any of the suggested changes therein, as this PR solves the problem that motivated #793 and does so in a more general and desirable manner.
