Fix some layout values

Cases indicated here correspond to portrait layout
so use else cases from sd/source/core/sdpage.cxx:3013 switch:

case 24/AUTOLAYOUT_HANDOUT3
nColCnt = 2; nRowCnt = 3;

case 26/AUTOLAYOUT_HANDOUT6
nColCnt = 2; nRowCnt = 3; break;

and so avoid some negative values for param given to
setHeight in xmloff/source/draw/sdxmlexp.cxx during sd tests
