Bug 6679 - api explorer creates false examples

Api explorer created false examples when yang has two data nodes with
same name in different containers or lists. It compared name of data
nodes rather than whole path to the data node which result to creting
examples of same types even if they should be different.

Fix examples by comparing the path to data node rather than just name
of the node.
