[NO ISSUE][ING] Only delete records if found

- user model changes: no
- storage format changes: no
- interface changes: no

details:
- Previously, change feeds that perform upserts and deletes
  used to blindly upsert a record for upserts and upsert
  an anti-matter for deletes in the absense of secondary
  indexes or filters.
- This lead to size blow out when there are a lot of deletes
  for keys that don't have values in the index.
- In this change, we only apply deletes strictly when a prevous
  value with the same key is found.
