tdf#152896 do not apply color shading twice
If a character theme color is shaded, Word writes this as w:themeShade
attribute of the w:color element. If the character also has
transparency, Word writes an additional w14:textFill element with
a w14:lumMod child element. In such cases the w14:textFill element
supersedes the w:color element.
The initial implementation of Fontwork import in commit
cbf30153a5c776e6d1ee26f2f83c8f77503eceb9 does it wrong. It replaces the
color itself but not the color transformation, so that the shading was
applied twice, once from w:themeShade attribute and the other time from
w14:lumMod.
The solution here is to reverse the order so that w:color is only
evaluated if w14:textFill is not present. Another solution would have
been to clear the color transformation vector before adding the values
from w14:textFill. I use reverse order here because it more clearly
reflects that w14:textFill supersedes w:color.
