tdf#130955 chart export: fix repeated custom labels

Do not add mCustomLabelText to aDataPointVector when we
write leading empty data points, it is enough to add them,
when we write data-point with style.

Note: this fixes also DOCX import, when the embedded charts
are imported by using ODF export in the background.

Regression from commit: 7d2c7e7af04d9604d86d2d605ef95b9abb10966c
(tdf#123206 Store custom label as chart:data-label)
