Fix bar category rendering for empty category The category in bar category axis can be an empty string (only one category can be empty for an axis as duplicates are removed).

\class QHBarModelMapper
\inmodule Qt Charts
\brief Horizontal model mapper for bar series.
\mainclass
Model mappers allow you to use QAbstractItemModel derived models as a data source for a chart series.
Horizontal model mapper is used to create a connection between QAbstractBarSeries and QAbstractItemModel derived model object.
Model mapper maintains equal size of all the BarSets.
Adding/removing value from the BarSet causes the the same change in the rest of the BarSets added to the same series.
\note Used model has to support adding/removing rows/columns and modifying the data of the cells.
