Surface choice name consistency errors sooner, before audit launch

Washington is going to work to have counties name contests identically (which may or may not be a challenge). I think in theory she did build some extra time in but had some straggler counties come in this morning. You also don't see that this is a problem until launch. So perhaps if we could give them visibility into this error well before launch, that would be ideal. These have to be done on such tight timelines already, I don't think we'll be successful in them finding an extra day. I know we've discussed a bigger project of allowing for casing differences and while it may be a lot of work, this may be something we see more and more (assuming we get more ballot comparison states and that's a big unknown).

With the fix for #1917 up for review, this is now less urgent
