"Preserved" option for "Store transformation" broken in 1.3alpha

Summary:

The "Preserved" option for "Store transformation" is not working in the alpha.

Steps to reproduce:

drawing.svg is a transformed group of paths. When the "Preserved" option for "Store transformation" is set, ungrouping should result in a collection of identical transformed paths. This happens correctly in v1.2, producing drawing_1.2.svg

But if you do the ungrouping in the v1.3alpha or even just open drawing_1.2.svg in the alpha, the transform is removed from the paths and the stroke widths are scaled, resulting in a group of lines whose widths are incorrect.

For anyone using Inkscape for generating scientific figures, this is major issue—the Preserved setting is essential for preventing errors like 2931.
