Steps to reproduce:

1. Open a Unity Project
2. Create a new Animator Controller via Assets > Create > Animation > Animator Controller
3. Open the new Animator Controller in the Animator Window by double clicking on it
4. Crete a Float Parameter called 'Test' via + > Float
5. Create a new State with right-click > Create State > Empty
6. Click on the new State
7. In the Inspector, check the 'Parameter' box next to Motion Time
8. Observe that the field is enabled and it has the 'Test' Parameter in the field
9. Rename the Parameter in the Animator Window by double-clicking on the name. Call it 'Test2'
10. Observe that the link to the Parameter in the Inspector is updated to say 'Test2'
11. Press Ctrl + Z to undo the Parameter name change

Actual results: The link to the Parameter in the Inspector has been broken and it still says 'Test2'. To have it reference the Parameter again, you will need to reselect the Parameter from the dropdown

Expected results: The link to the Parameter is not broken and it updates to match the Parameter
