    Description

      We don't do this for couchstore as complete prepares do not need to be sent/received. This was not spotted in review of this change - http://review.couchbase.org/c/kv_engine/+/160292. In addition we are currently moving the purge seqno for collection items purged in implicit compactions which is not necessary either.
