1. Unify behavior of UnionList, DifferentList, UnionIDs, DifferenceIDs functions when empty list is passed as parameter - no exception should be raised in this case.

Browse Source 
2. Avoid raising exception in DifferenceList, DifferenceIDs functions if the group is empty
3. Fix bug in DifferenceIDs function - bad list of IDs is contained when the group is cleared.
