Block number was NOT being signed over, this meant any node could tweak it and cause receiving nodes to consider the proposal incorrect. We fix this by fetching the parent node using the last archive root (which required adding new indices to the archiver) and computing the block number by adding one to it. As for attestations, the block number was not used at all, so we could remove it. Fixes A-128
