lok: You can't assume that destroyView would only destroy one view
In case you have some in-place clients (e.g., Math in-place editing
is active), destroying the parent view would also destroy children,
and then both numberOfViewsChanged (called from doc_destroyView)
must tolerate 0 as a valid input, and lok_doc_view_destroy must
make sure to destroy the document after the last views had gone.
