    Resolves: tdf#108654 check nTabNo against maTabData size
    
    ScViewData::DeleteTab() and DeleteTabs() never did that and worked by accident
    for which commit 73dec49802ef8fc42c5719efaa42a33cde68e569 removed the
    grounding..
    
    squash this into it too:
    
    assert(nTab < static_cast<SCTAB>(maTabData.size())); cause of tdf#108796
    
    Have a dev friendly abort instead of a deep throw in case of the unexpected.
