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

[Franci5co5aoco]

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.
