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.

Tree-SHA512: 3c8fb160265780d1334e856e853ab48e2e18372b8f1fc71ae480c3f45317048cc1fee0055d5c58031981a91b9c2bdbeb8e49a889d04ecba61729ce8109f2ce3f
