Revert "DE2347 - Remove tenantId index from recordHash as intended"

This reverts commit 6718f6f8388ca42d85c6403129be29d2c36852e8.

Need to keep the index because purging the data in recordHash,
which remains shared across tenants in ingestion_batch_job,
requires a full-table-table scan when the index is absent.
That in turn breaks in CI which prohibits full table scans.
