CommandProcess ClearOutbox will send a message regardless of if its been sent before

@iancooper I was wondering if this was intended

if you run ClearOutbox with an Id of a message there are no checks at the Command Processor level to see if it has already been dispatched, I understand that this may be on Purpose (Re dispatching messages), I was just wondering if you think it would be a good idea to add a bool to the Clear Outbox Method to turn on a already dispatched check?

I understand that systems need to be idempotent and be able to consume duplicate events, and I can only see this being of benefit when someone Deposits into the outbox and then for some reason there is a wait between that and Clearing the outbox where the Outbox sweeper could get in the middle. not urgent just wanted your thoughts on the matter.

I guess the trade-off is on the cost off querying the Outbox. I don't have an objection to adding a deDuplicate bool to Clear and defaulting it to false, and then letting folks choose to check if they want to.

That was my thoughts, don't enforce it but give the option, again, not a big issue but a nice to have
