[2.1.x] Fixed #29499 -- Fixed race condition in QuerySet.update_or_create().
A race condition happened when the object didn't already exist and
another process/thread created the object before update_or_create()
did and then attempted to update the object, also before update_or_create()
saved the object. The update by the other process/thread could be lost.
Backport of 271542dad1686c438f658aa6220982495db09797 from master
