0027391: BRepLib::EnsureNormalConsistency() raises exception in case of asynchronious PolygonOnTriangulation problem

Browse Source 
additional check have been added to BRepLib::EnsureNormalConsistency() func.
Any edges with two adjacent faces will be skipped (while updating of their normals) if the number of discretization points (nodes) will be different for each of this faces on this edge.
