What happened?

mautic.CRITICAL: Uncaught PHP Exception Doctrine\ORM\ORMInvalidArgumentException: "Detached entity Mautic\LeadBundle\Entity\Lead with ID #51245 cannot be removed"

How can we reproduce this issue?

Saw this in a queue system.

Step 1: Send a bulk contact edit API request with the same contact ID for edit twice
Step 2: Witness crash

Error stems down to BatchIdToEntityHelper being smart and being able to load an entity once and assign it twice in the returned entity map.

However, CommonApiController::processBatchForm assumes that entities appear and detaches them while processing - so if an entity appears twice - the second time round you are working on a detached entity.

Likely processBatchForm needs to update $entities if the one being detached is still in it, to replace it with the new one.
