Problem and fix for `constraint.render.type: 'pin'` in non-minimized code for version 0.20.0.

[Vaiok]

This is for the non-minimized code of version 0.20.0.

Description

The pin type for constraint rendering is causing an error in the Render.constraints function because end.x and end.y are only defined in the else block when the if condition testing constraint.render.type === 'pin' fails.
The following code

if (bodyB) {
    end = Vector.add(bodyB.position, constraint.pointB);
} else {
    end = constraint.pointB;
}

should be moved out of the else condition and put directly beneath this code.

if (bodyA) {
    start = Vector.add(bodyA.position, constraint.pointA);
} else {
    start = constraint.pointA;
}
