> DataNode.getChildren() API returns null and empty set if there are no children in it
depending on when the API is called. DataNode.getChildren() API behavior should be changed
and it should always return empty set if the node does not have any child
> *DataNode.getChildren() API Current Behavior:*
> # returns null initially
> When DataNode is created and no children are added yet, DataNode.getChildren() returns
null
> # returns empty set after all the children are deleted:
> created a Node
> add a child
> delete the child
> DataNode.getChildren() returns empty set.
> After fix DataNode.getChildren() should return empty set in all the above cases.
