Steps to reproduce:
1) Create a new project
2) Create Cube gameObject. Drag to project browser to make a prefab
3) In Hierarchy, Select Cube > Add Rigidbody
4) In Project browser, Select Cube > Add fixed joint
5) In Hierarchy, Select Cube > Revert added Rigidbody and apply removed Rigidbody component
6) Press Ctrl + Z or Edit > Undo

Actual result: Multiple rigidbody components are added to Cube gameObject

Expected result: Only one rigidbody component can be added to a GameObject
