Node copies WAL files from the WAL dir into the WAL archive dir incorrectly after WAL archive files are deleted after the node is stopped.

Workload: 1. Cluster is up and data is uploaded into caches. 2. Load to generate a lot of files in WAL archive 3. Stop a node and delete all files from the WAL archive 4. Restart the node

Impact/symptom: Excessive logging (unnecessary data copy) and incorrect files copied to WAL archive

Fix: Move files using the last archived segment index to the WAL archive instead of copying from start
