    tdf#125893 DOCX import: fix "half" contextual paragraph spacing
    
    Always ignore own top margin setting of the actual paragraph
    with contextual spacing, if the previous paragraph is identical.
    I.e. in that case, too, when the previous paragraph has no
    contextual spacing, like MSO does.
    
    Note: PARA_SPACE_MAX mode hasn't included this modification,
    yet, so only ODT documents converted from DOCX use it at the
    default setting.
