Description

When a tween's duration is 0, the object being animated disappears.

Example Test Code

Using https://labs.phaser.io/edit.html

var config = {
    type: Phaser.AUTO,
    width: 800,
    height: 600,
    parent: 'phaser-example',
    scene: {
        preload: preload,
        create: create,
    }
};
var game = new Phaser.Game(config);

function preload () {
    this.load.image('block', 'assets/sprites/block.png');
}

function create () {
    var image = this.add.image(200, 300, 'block');
    this.tweens.add({
        targets: image,
        x: 300,
        duration: 0
    });
}

Change the duration to anything greater than 0, and it works - but when duration is 0, the sprite just disappears instead. I'd expect it to just jump to the end of the tween instantly if the duration is 0.
