Unity crashes when undoing the deletion of UI object that was a part of prefab
Reproduction steps:
1. Open project ("Reproj project").
2. Drag prefab "Canvas" to the scene.
3. Delete gameobject "Text" from Canvas that is in the scene.
4. Press "Undo".
Expected result: Object will be recreated.
Actual result: Unity crashes.
Notes: Crash stacktrace varies with different UI objects. Tried to reproduce with other objects (not UI) but the problem was not reproducible with them.
Reproduced on: 2017.2.0a1, 2017.2.0b8, 2017.3.0a5.
Works fine on: 5.6.3p2, 2017.1.0p5.
