BUG: Moving between slides doesn't work properly when a slide is duplicated

**Version:**
0.1.5

**Are you able to reproduce the bug from the demo?**
Yes.

**What is the expected behavior?**
When `Infinite` option is checked and I duplicate a slide using the tooltip or copy/paste it using the Layer Manager and I click the arrow icon (next or previous) the slide moves on one slide next or previous in the correct order.

**What is the current behavior?**
When `Infinite` option is checked and I duplicate a slide, clicking the next/prev button moves on the slides randomly (not in the right order).

**Steps to reproduce**

1 - Drag and drop a Slider Component into the canvas.
2 - Select the Slider component and check the 'Infinite' option (important).
3 - Place a text component on each slide: '1' (for the first slide), '2' (for the second) and '3' (for the third) in order to differentiate them.
4 - Click on a slide, the tooltips appears, click on duplicate icon, the slide is correctly duplicated (you can check it in Layer Manager).
5 - Now, click several times on the next slide button (>).
=> The slides doesn't move on the correct order.
