If a long reorganize occurs farther back than the last saved recent block hash (currently max 20 are saved) a full rescan is triggered since there is no guarantee the previous blocks weren't also removed in the reorg. In this case, the address manager was set unsynced, but transaction history was not rolled back as well. This commit corrects this by unconfirming all transactions but those in the genesis block.
