Fix T58993: Duplicating after setting a rigid body world crashes Blender.
There is no guarantee that object in rigidbody collection already have a
valid rgigidbody data when rebuilding deg relations, that is often
generated on-the-fly by actual rigid body simulation.
Note that this can be an issue when generating deg relations I guess...
But at least it won't crash anymore.
