Description
When many updates to the same entity are queued, the SyncIndexWithObjectChangeProcessor will always keep the first representation of an entity that it fetched from Doctrine, causing all subsequent updates to resend exactly the same data.
This happens because Doctrine's manager keeps a cached version of the entity and reuses that version for subsequent calls to "find".
The solution is to clear all managed entities so Doctrine will re-fetch the entity from the database.
I will submit a PR.
