    sw: layout: fix table split loop caused by RemoveFollowFlowLinePending
    
    In no_view.odt, the table 1340 does RemoveFollowFlowLine(), then splits
    again, and by the time Split() returns, its flag
    m_bRemoveFollowFlowLinePending is set and so in the next
    SwTabFrame::MakeAll() it will do the same thing again, until eventually
    it hits
    layact.cxx:544: LoopControl_1 in SwLayAction::InternalAction
    
    The flag is set during lcl_RecalcSplitLine(), in SwContentFrame::Cut(),
    which operates under the assumption that there are no other cells in the
    follow flow line that may contain content frames.
    
    This only happens if "Verdana" and "Arial" fonts are available and not
    substituted with "DejaVu Sans" etc.
    
    (regression from c4af8b0f106f31b6e79a145bc4ab83bb6a55c808)
    
    Unfortunately this uncovers another pagination bug in testTdf88496
    which was hidden by this flag being set from text frames that shouldn't
    exist anyway.
