The methods HasAncestorFaceOn1() and HasAncestorFaceOn1() return true only in the case when their first argument is the new edge built from intersection curve and not an existing common edge. PCurveOn1() and PCurveOn2() have been removed. Methods PCurveOn1() and PCurveOn2() removed from BRepAlgo_Section class. Added test case bugs/modalg_5/bug23881
