#4882: GetTopoGeomElement{s,Array) return unsigned elements

 While working on a testcase for #4881 I realized that GetTopoGeomElements,
 and its friend GetTopoGeomElementArray both drop the sign of element
 identifiers in the relation table. The documentation does NOT mention
 element_id sign so this is not necessarely a BUG but for sure it is a
 limitation that we probably want to overcome somehow. Maybe by adding an
 optinoal parameter to the function to retain the elements sign..
