Fix use of FindTabbedBrowser when handling windows.create calls.

Fix use of FindTabbedBrowser when handling windows.create calls.

In practice, this particular call to FindTabbedBrowser will only happen for Ash-in-metro, so using the default host desktop type (as was done in http://crrev.com/168064) is guaranteed to be the wrong choice. Forcing HOST_DESKTOP_TYPE_ASH would be correct for this specific case, but using the currently active desktop (which will always be Ash) will also work and is more consistent with other places where a browser needs to be found.

Don't sweat it. I've had my fair share.
