“The serialized array of [SerializeReference] objects is missing entry for Refid -2” error is thrown when saving a prefab with SerializeReference overrides and ShowOverrides is enabled

Reproduction steps:
1. Open the attached “BugRepro” project
2. Open the “Assets/Scenes/SampleScene.unity“ Scene
3. Open the “GameOject” prefab in context mode (click the Arrow to the right of the prefab instance)
4. Enable the Show Overrides toggle in the Prefab bar
5. Change the value to 6 in the Inspector window
6. Save the prefab (Ctrl/Cmd + S)
7. Observe the Console window

Expected result: No error is thrown
Actual result: “The serialized array of [SerializeReference] objects is missing entry for Refid -2” error is thrown
