    sfx2: fix VBA crash when disposing SfxBaseModel
    
    Crash on WNT in CppunitTest_sw_globalfilter testSkipImages()
    
    SfxBaseModel::dispose() calls some event listener that deletes the
    BasicManager instance; unfortunately SfxObjectShell_Impl has a
    SfxBasicHolder member that still refers to the deleted BasicManager
    and then something calls vba::getVBAServiceFactory()...
    
    Try to fix that by clearing the SfxBasicHolder member via SfxListener.
