feat(#646): Use next due date when selecting a new one
requested to merge 646-clicking-on-due-date-opens-first-due-date-instead-of-the-current-one into development
Before, when selecting a due date for an item, we used to pre-select the original due date of an item. For items with a recurrence pattern, the first due date can be weeks or months before the current one - which is quite confusing when you want to select a new due date.
We change this so that the editor now shows the current due date of the item, which is way more intuitive.
