> Added code to call CloseAsh in place of closing secondary widgets on Windows.
> Here is what happens in attached bug:
> 1. UserManagerView (Profile view) adds a reference to browser process by calling StartKeepAlive.
> 2. UserManagerView is a secondary widget.
> 3. Current code for windows does EnumWindows for closing all secondary widgets in CloseAllSecondaryWidgets, which works only for desktop mode.
> 4. In Chrome on ASH EnumWindows doesn't do anything as they are not regular windows.
> 5. Because UserManagerView doesn't get chance to close through CloseAllSecondaryWidgets, it doesn't release reference and we browser process keeps running.
> 
> CloseAsh closes all child widgets, which might be a overkill but works for now.
