Multiple Completed and Passed statements could be sent for one registration

[thomasturrell]

I believe that the cmi5 spec requires that only one Completed and or Passed statement is sent by the AU.

The AU could use the agent xAPI state resource to store if it has previously sent Completed or Passed statements. I don't believe the AU should attempt to check the existence of the Statements in the LRS because some LMS might prohibit an AU from requesting statements.

This can be resolved by the same local storage mechanism in issue #8

It should handle users that logged in using different devices too. However I can see that this might be out of scope.

The AU also has the option to use the State API, which would be a better place than local storage for that situation.

Agreed that State API is better place to store data that may need to be shared across devices.
