Fix a crash in FullscreenExitBubbleController when the user clicks the "Exit full screen" button.

The crash was due to the fact that Browser::OnDenyFullscreenPermission causes BrowserWindow::ExitFullscreen to be called, which causes the FullscreenExitBubbleController to be destroyed. [FullscreenExitBubbleController deny:] was sending a -hideSoon message to its zombie self following the call to Browser::OnDenyFullscreenPermission.

BUG=101835
TEST=The browser doesn't crash when you click "Exit full screen" on a fullscreened page.
