    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.
    
    (regression from 2660d24a07866e083c5135ea263030f3e3a2e729)
    
    (cherry picked from commit 96ae2a3300811897c24cccb20f8c2faf382483df)
