tdf#114596 dbaccess: fix mysterious dataloss bug
OBookmarkContainer actually re-uses the reference count of
ODatabaseSource, so converting ODatabaseSource::m_aBookmark to Reference
created a cycle, which somehow causes the dataloss, because evidently
something as important as storing the data must be done in the
destructor.
