    Reuse the transaction before getting messages

    The message get helper for claims used its own connection and ran
    outside the transaction where the 'claiming' happened. This caused the
    get to fail at retrieving the messages because the query was being
    executed 'before' the transaction.

    This patch fixes the aforementioned issue and also ensures that records
    ids are 'int' before calling `message_encode`.
