Log:
- fix a mistake : stop_date = document.getStartDate()
- findEffectiveSpecialiseValueList was not using Breadth First Search like
  findSpecialiseValueList. Now both code have the same behaviour
- findEffectiveSpecialiseValueList was not really using effective model, not
  it use it, and if no effective model are found, an empty list is returned
- in case where no effective model are found, getEffectiveModel return None
  (instead of self). If getEffectiveModel is call with None stop_date and
  start_date, self is return
