Improve 32K limit tests

Some operations were previously limited to 32,768 parameters,
such as getDataNodesForMultipleXpaths. After this limit was lifted,
the tests only verified that database exceptions were not thrown.
This commit improves the tests by verifying that the operations
return or delete the expected data.

- Create 33,000 data nodes
- Verify that getDataNodesForMultipleXpaths returns 33,000 nodes
- Verify than deleteDataNodes deletes 33,000 nodes
