Subject: [PATCH 3/5] rhbz#1444437 gnome-documents finalize may not occur
 immediately
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

when LOK Widget is destroyed, it may instead happen during GC of javascript,
like in the in gnome-documents case, but "destroy" will be called promptly. So
close documents and office in destroy, not finalize
