views: Restore to old behaviour of Widget::ReparentNativeView().

Restore the previous behaviour of Widget::ReparentNativeView() of parenting the
window to the root-window, instead of detaching it from the window tree. This is
necessary since copy-requests on the window cannot be performed when the window
is detached from the layer-tree. This breaks, among other things, capturing
thumbnail of a page when it is backgrounded.

LGTM - I thought that code was there for a reason.
