vg_common_svg: colors unpremultiplication added before saving into edj file

Colors were premultiplied first when reading from the svg file and
second when saving into edj file. As the result svg files with the opacity < 1
could be uncorretly displayed (only when the color and the opacity were
given in the same node).
