Inconsistent constraint behavior on Configurable Joints when used with Duplicate objects
Reproduction steps:
1. Open the attached project named "Case_1145289"
2. Select the Sphere in the BlankScene and enter Play mode
3. Move the Sphere on the Z-axis. Hinge Joint explodes due to no constraints
4. Duplicate the Sphere and Disable the original Sphere's gameObject
5. Move the Sphere's duplicate on the Z-axis
Expected result: Joint behaves the same way as with the original Sphere
Actual result: Joint behaves completely different when used with a duplicate Sphere
Reproducible with: 2017.4.26f1, 2018.3.14f1, 2019.1.1f1, 2019.2.0a14
Notes:
1. While testing with 2017.4.26f1 noticed that re-enabling the Sphere's gameObject is enough to completely change its behavior. Shown in Track_1145289_V2
2. If Both the original and the duplicate Sphere gameObjects are disabled then behavior can be reversed if the Duplicate Sphere is Enabled first. Shown in Track_1145289_V3
