Collision area geometry does not get recalculated when Actor dimensions change

[eonarheim]

Steps to Reproduce

Extend and actor and do not call the super constructor, try to collide this with another actor

See https://github.com/dgparker/excaliburjs-breakout for an example

Work around

class Paddle extends ex.Actor {
   public game: ex.Engine;
   constructor(game: ex.Engine) {
     super({
        x: game.drawWidth / 2,
        y: game.drawHeight - 40,
        width: 200,
        height: 20
     });
   //   this.game = game;
   //   this.setWidth(200);
   //   this.setHeight(20);
   //   this.x = this.game.drawWidth / 2;
   //   this.y = this.game.drawHeight - 40;
     this.color = ex.Color.Chartreuse;
 
     this.collisionType = ex.CollisionType.Fixed;
 
     this.addInputListener();
   }
  ..
}

Expected Result

Actors should collide and this method of setting properties should work.

Actual Result

No collision
