[UI] Destroying Canvas that has another Canvas as child crashes in UI::Canvas::GetRenderMode()

UI

-

Destroying a Canvas that is added via a script on an object that has a child with Canvas, crashes Unity Editor.

Steps to reproduce:
1) Open the attached project.
2) Open 'Main' scene.
3) Enter play mode.
4) Press 'Space'.

Unity instantly crashes in UI::Canvas::GetRenderMode(). The destroyed Canvas is added to an empty object via script. If it is manually added to the object before runtime, the crash doesn't occur.

Reproduced on:
5.6.0b7, 5.5.1p3, 5.4.4p3

Did not reproduce:
5.3.7p4, 5.2.4f1
