This PR removes the use of a bloom filter during snap sync. Bloom filters are nice, but for snap they don't really help that much. We only ever want to do a bit of light healing on top of mostly correct state.
In practice, however, if the user restarts the node, it will kick of an entire trie-iteration to filll the bloom filter, which is a bit counterproductive for a feature that was meant to accelerate things by keeping the disk IO down.
