Further separation of legacy dedupe finder from code to be cleaned up

Overview

Further separation of legacy dedupe finder from code to be cleaned up

Before

Legacy version still very entangled

After

Further progress on giving the legacy extension function a static copy of the code, allowing clean up in the core code

Technical Details

The legacy extension is enabled on all sites (unless they actively disable a hidden extension ) at this stage and is also the code that is heavily tested through a range of tests. So the 'live' version has the heavy test cover
