tdf#31488: Background fill changes its color when saving a PPTX file to ODP

For a gradient fill we need to generate a name because
ODP export works with this name.
In case of shapes it works because when fill attribute
changes some internal name generation is triggered.
The same thing doesn't work for slide background
so generate this name explicitely in oox code.
