Local fix

Problem summary

• USERS AFFECTED:
  Commerce V7 users using web or dialog activities.
  
  PROBLEM ABSTRACT:
  Marketing dialog activities may cause
  ConcurrentModificationException to appear in the logs. Customers
  are not participating in dialog activities in which the trigger
  conditions have been met, or web activity targets are not
  evaluating correctly when the target conditions have been met.
  
  BUSINESS IMPACT:
  Web or dialog activities are not functioning as expected.
  
  RECOMMENDATION:
  

Problem conclusion

• The marketing engine code needs to ignore events that are
  associated with activities for which the start date has not been
  reached, or the end date has passed.  The code was fixed to
  correctly remove these events and not cause a
  ConcurrentModificationException.
