Merge #11565: Make listsinceblock refuse unknown block hash

659b206 Make listsinceblock refuse unknown block hash (Russell Yanofsky)

Pull request description:

  Change suggested by @theuni  who noticed listsinceblock would ignore invalid block hashes causing it to return a completely unfiltered list of transactions.
