Fix prepare_payload_for_reinvocation in invoke

[mircealam]

Description of changes:

This is for the use case where we are leveraging cfn invoke.
Before the fix only the callbackContext was passedin leading to a situation where if the model is updated and the handler emits a progress event we would end up losing recoding the updates that were made (and making the handler fail for those instances).
One such example is when we are creating a resources and there are multiple API calls needed to materialize this resource with a progress event being emitted between this API calls and one of the later API calls needed info returned by the earlier calls and persisted in the model.
