App/Toponaming: GeoFeature - fixes #13009 - fixes #13248

* Restored previous logic of GeoFeature::getElementName()
 * Added precompiler directive to use the old logic if FC_USE_TNP_FIX isn't defined, otherwise use the new logic
 * Reworked SketchObjectTest::getElementName() as a consequence of the previous points
