Can't stack up Camera.move()'s only the first works

[eonarheim]

Steps to Reproduce

var game = new ex.Engine({
   width: 600,
   height: 600
});

game.isDebug = true;

game.add(new ex.Actor({x: 0, y: 0, width: 100, height: 100, color: ex.Color.Red}));

game.start(loader).then(() => {
   game.currentScene.camera.move(ex.Vector.Zero.clone(), 2000, ex.EasingFunctions.EaseInOutCubic).then(() => {
      game.currentScene.camera.move(new ex.Vector(600, 600), 2000, ex.EasingFunctions.EaseInOutCubic)
  })
   console.log('started');
});

Expected Result

Camera should move to (0, 0) and then move to (600, 600)

Actual Result

Camera only moves to (0, 0)
