Wrong ChoiceSet listeners being called when queueing PresentChoiceSetOperations

[renonick87]

Bug Report

If multiple PresentChoiceSetOperations are queued with the ChoiceSetManager, then the listeners from later ChoiceSets can end up being called on earlier ChoiceSets. This is likely because the operation class is using a reference to the manager's current pending ChoiceSet instead of cloning the data.

Reproduction Steps

1. Present a ChoiceSet with the manager and while it's being presented, queue another ChoiceSet to be presented. Provide an onChoiceSelected listener for both.
2. In the HMI, select one of the available choices from the first ChoiceSet.

Expected Behavior

The listener for the first ChoiceSet is called.

Observed Behavior

The listener for the second ChoiceSet is called.
