[FIX] web_editor: fix makeLayoutInfo

Issue

        - Install Website
        - Edit your website

        Do this 8 times:
        - Add the block "Image - Text" under each product
        - Make image on left smaller and text longer
        - Edit the size/color of the title and the description

        There is some case where it will crash

Cause

        We override the method who gets the editor:
        `x = $('[data-note-id="' + list.last($target.attr('id')) + '"]');`
        When there is more than 9 editors in the page
        (because we edited 10 different HTML fields), we reach the
        editor with ID 10 but the code erroneously will not find the
        editor with ID 0

Solution

        Use this instead:
        ```
        x = $('[data-note-id="' + list.last($target.attr('id').split('-')) + '"]');
        ```
