"object to path" removes class attribute

[Aurèle Duda]

Linux mint and Inkscape 0.92+devel (733a237, 2017-10-27)

When a object is changed to path using "object to path", it lost his class attribute if any.

Open test_class_objecttopath.svg
select the circle or the rectangle
open xml-editor : a class attribute is set (class="test")
use object>object to path
look at the path in xml-editor : the class attribute has disappeared.

Test case and Patch provide
