DescriptionFix crash in WebContentsViewAura::WindowObserver that happens when switching tabs. The exact repro steps were:
1) open an empty page
2) print preview
3) open a new tab
4) go back to original tab
5) close print preview
6) switch to the new tab
The crash happened at step 4 because the second tab got removed from the same root window as the print preview's observer. We weren't unobserving all the children of the root window at that point.
