Sensor shapes with ccd enabled don't ignore collisions and get stuck

[sarunasi]

When shape has either sensor = true or collisionResponse = false and body has ccd enabled (ccdSpeedThreshold = 0) it starts colliding with other bodies even though it shouldn't. It also gets stuck inside them.

Example: https://jsfiddle.net/jk05zv1u/13/
Both shapes are sensors.
The top shape is without ccd and botom one is with ccd enabled.
Top shape works as expected.
