StepQueryWithIterator could pass ticket to interested methods

[mscappini]

I think the StepQueryWithIterator class could pass the authenticatedTicket to the SaveMessage and RetrieveMessage methods in lieu of the current ticket and step. This would be useful because (in my implementation, for example) the ticket I use inherits from the AuthenticatedTicket class and is tracked in memory while storing a state (associated with the ticket) that can be used throughout the step process. So passing the instance of the ticket would save one the trouble of looking up the authenticated ticket by the ticket ID in certain implementations.

Yes it would be probably a better design.
