JSON list support when updating multiple datanodes

updateDataNodesAndDescendants if supplied with a JSON list such as
 {"branch": [{"name":"Name1"}, {"name":"Name2"}]}
would only replace the first node /test-tree/branch[@name='Name1'],
and ignore any remaining list items. This is caused by the use of a
legacy buildDataNode, which returns only a single DataNode from JSON,
even if the JSON contained a list.
