Intersection with Circle always includes end of LineSegment2

Using r36:
>>> from euclid import Circle, LineSegment2
>>> c = Circle(Point2(0.0, 0.0), 1.0)
>>> s = LineSegment2(Point2(-4.0, 0.0), Point2(-3.0, 0.0))
>>> s.intersect(c)
Point2(-3.00, 0.00)
Expected value is 'None' since segment does not intersect circle.
I attach suggested patch which fixes the issue (and seems not to introduce new
ones, though is not fully tested).

I have a similar issue with a Ray2, probably caused by the same underlying code:
>>> c = Circle(Point2(4,5), 1.0)
>>> r = Ray2(Point2(13.0, 5.0), Vector2(1.0, 0.0))
>>> r.intersect(c)
Point2(13.00, 5.00)
