Fix threshold for no for non v1 side contracts

[Callum-A]

Need to get some eyes on this to check my logic all works clear.

New logic is no votes can reject proposals when they are greater than 1 - threshold. (Or for absolute count total_weight - count).

Going to need some eyes on this to sanity check.

Nice, the main issue is it checked if no passed threshold, when it should check if no passes 1-threshold.

This is a good fix.

(The buggy version would refuse to mark as rejected some proposals that would never pass, but it wouldn't let them pass, so this is an enhancement and not security critical)

Just need to add the logic around the case where the passing threshold is 100% as discussed in Discord. #221

Looks great! Thanks for all help iterating on this.

Did we reach 100% test coverage for the does_vote_count_reach_threshold()

for both multi-sig and cw3-dao. we probably have but I'm just curious here

Besides those comments, overall looks good and given we're passing the old tests this means this is working as expected.
