copies: properly match result during changeset centric copy tracing
By filtering "during" the iteration we were excluding rename information that
were not in the matched set but that file served as base information for the
matched set.
We now do all copy tracing matching at the end of the process to ensure we raise
proper result.
If we were aggregating information top down instead of bottom up we could do
filtering during processing. However, we don't.
