QString QSafeTextGenerator::generateData() calls old code path

While trying to figure out, why testBitmapFileFormats() in tst_qsafelayoutgenerator.cpp didn't seem to produce an error when the format was changed in QSafeCompressedImageGenerator::generateData(), it turned out that it was never called for static text as intended. The call in

QString QSafeTextGenerator::generateData(QSize &size, const Item *item) was to an old code path.
