feat(prot): don't produce empty blocks [AC-1189]
Closes AC-1189. Do not produce blocks when the network is quiescent. Specifically, when a subnet is finalizing block N (during begin block N+1), do not send an anchor if block N contained nothing besides a directory anchor. This breaks the loop of BVN anchor -> DN anchor -> BVN anchor -> etc.
I have verified that this prevents growth of the database. Tendermint still produces blocks, but they are empty and result in no changes to the database.
