Simplify the code

TextPagePrivate::correctTextOrder was running makeAndSortLines + calculateStatisticalInformation to calculate the tcx, tcy
to pass it to XYCutForBoundingBoxes and then in XYCutForBoundingBoxes we were doing the same but just for when countLoop was not 0, thus
if we remove the first code and remove the check for countLoop being not 0 we end up with the same behaviour
