wallet: Avoid use of Chain::Lock in importprunedfunds
This is a step toward removing the Chain::Lock class and reducing cs_main locking. This change only affects behavior in the case where wallet last block processed falls behind the chain tip, in which case the "Block not found in chain" error will be stricter and not allow importing data from a blocks between the wallet last processed tip and the current node tip.
