tdf#127304 Chart: fix rotation of multilevel axis labels

If the first level of horizontal category axis labels
is rotated vertically, then the other levels should not be
rotated.

Regression from commit: 23c0b3e13f88d6d71d528777d4f86f50c0766672
(tdf#107074 uncommenting createLabels for the axis fixes the issue)
