Close the window before destroying it?

[tapted, 2014/06/19 02:00:13]

Done. yep - the test will need to see the notifications otherwise sent from
~aura::Window() (except here they will eventually be coming via
NSWindowDelegate). I think the ownership model this will be testing is somewhat
analogous to [NSWindow setReleasedWhenClosed], but I haven't plumbed that
through yet. Since ReleasedWhenClosed is default for NSWindow, this is now just
a close with a DCHECK. I'll explore this more deeply when I bring up more of the
widget unittests.
