Steps:
1. Create a GameObject with HingeJoint and Rigidbody on it
2. Turn it into prefab
3. Remove both components
==>
They appear as overrides
4. Right click on HingeJoint and Revert it
==>
"Error removing component when merging Prefab changes: Can't remove Rigidbody because CharacterJoint depends on it" error message appears (It is OK)
HingeJoint reverted
Rigidbody re-added again

Expected:
Dialog should appear telling that cannot perform revert operation (as in other cases, like when removing Rigidbody when other components depend on it)
HingeJoint should not be reverted
Rigidbody should not be re-added
