    Store cells credentials in transport_url properly

    Looks like we need to store the decoded version in the
    database, not the encoded version...ie:
        rabbit://the=user:the=password@hostname:5672//
    instead of:
        rabbit://the%3Duser:the%3Dpassword@hostname:5672//

    Once we build up the transport_url and transform it into
    a string, we just call unquote to convert %xx escapes back
    to their single-character equivalent.
