Fix uouv on oom on object allocation
We should initialize object handlers before trying to allocate more memory, because if we OOM we'll look for the free_obj handler which has not been initialized. Furthermore, free_obj can run before the object is fully initialized, requiring guards for potentially unset fields. Fixes GH-11734
