rhbz#1163106: tdoc_ucp: fix life cycle of OfficeDocumentsCloseListener

The tdoc_ucp::OfficeDocumentsManager lives until the service manager
is disposed on shutdown, but if the database stuff isn't disposed in due
time then a document may call the notifyClosing() on the listener after
the OfficeDocumentsManager dies; probably something is leaking the
ODatabaseContext...
