When object is just created, it is not yet assigned an OID, but can be
reachable from other objects. The code that processes transaction can
reach to that new object and try to PActivate/PDeactivate it. And
currently PDeactivate will drop the object state completely.

Another example of object without an OID is Bucket embedded into a Tree
object. There, the code that scans the tree can reach to that bucket and
try to activate/deactivate it, leading, again, to dropping state of that bucket.

-> Fix it.
