smartart import: handle multiple <a:schemeClr> in <dgm:fillClrLst>

The TODO in the ColorFragmentHandler ctor was right: we only handled the
last <a:schemeClr> child, but there can be multiple one.

Use them based on the index of a shape in a <dgm:forEach> loop.

Move the TODO to the only place which still assumes a single color in
the color list.
