Duplication now uses new Query Model

Updated the duplication functionality to use the new Query Model.
Code clean up on duplicate method.

Removed commented code ( for versions using QueryResource REST API).
Fix for [SKU-1067] and [SKU-1068]

Calls to query.enrich are causing an Uncaught TypeError in QueryActions.

If we disable the call to query.enrich on the method calls to  show_mdx and post_mdx_transform it works as expected.
