Summary of changes:
  1. When a time-based trigger is evaluated and 'onTriggerCompleted()' is called, we no longer make redisplay messages available to avoid duplicate redisplay of a same message.
  2. Modify the logic of 'makeRedisplayMessagesAvailableWithTriggers()' so that a message can be redisplayed only if at least one trigger has changed or a new trigger is added.
  3. 'onTriggerConditionChanged()' now accepts a new parameter 'triggerId' that indicates the time-based trigger that fires.

…r is added when there is only dynamic trigger
