testPolygonCircle and testCirclePolygon always return true if Polygon has width/height 0

[fabiopigna]

var V = SAT.Vector;
var C = SAT.Circle;
var B = SAT.Box;

var circle = new C(new V(50,50), 20);
var polygon = new B(new V(1000,1000), 20, 0).toPolygon();
var response = new SAT.Response();
var collided = SAT.testPolygonCircle(polygon, circle, response);
console.log(collided); //output true

If width or height of the polygon is 0 the result is always true, despite of the position of the elements.
If the two elements are both circles or polygons it works.
