Bugfixes

• #12314: SlotSet events will be emitted when the value set by the custom action is the same as the existing value of the slot. This was fixed for AugmentedMemoizationPolicy to work properly with truncated trackers.

  To restore the previous behaviour, the custom action can return a SlotSet only if the slot value has changed. For example,

  class CustomAction(Action):
      def name(self) -> Text:
          return "custom_action"
  
      def run(self, dispatcher: CollectingDispatcher,
              tracker: Tracker,
              domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:
          # current value of the slot
          slot_value = tracker.get_slot('my_slot')
  
          # value of the entity
          # this is parsed from the user utterance
          entity_value = next(tracker.get_latest_entity_values("entity_name"), None)
  
          if slot_value != entity_value:
            return[SlotSet("my_slot", entity_value)]
