Update to unselect method to support "select2-removing" triggers.

Browse Source 
The goal here is send off a triggered event to a subscriber that an
element is going to be removed. It hasn't removed yet but would be
after the event fires. I have also added logic to determine if a
subscriber has prevented default. This will prove useful in the future
if a subscriber needs to extend the functionality for other usages.
