Reverting the addition of the contest table.

@DSASanFrancisco/portal-members @dbolson I think we need to discuss the schema around this more.

As I thought about it more, I think a "Google Forms" model is the wrong approach. I think we should link things to meetings instead of some "election." Amendments are very dynamic and it isn't clear how we would vote on amendments to amendments during a meeting with this approach.
