A bug currently makes the carousel snippet collapse/disappear when its
active contents are removed. This happens because after the removal,
the carousel no longer has an active item.
The solution that was chosen was to not allow the removal of slides
unless using the dedicated option which is there for that. This solution
has the advantage to also allow users to create empty slides (using a
background image for example) by simply removing the columns inside.
Note: Newly created carousels will include the oe_unremovable class on
their slides. As such they will no longer depend on isEmptyAndRemovable
checking them for having a carousel-item class on the parent.
