Also added a comment in onItemMove explaining why that method
does not call doTheUpdate().

Dragging is not supported neither by TalkBack or the accessibility
framework at the moment. So we need custom actions to be able
to change the order of the locales.
Also, the remove functionality is difficult to discover and use
with TalkBack only, so we are also adding a "remove" action.
It only removes one locale at the time, but most users don't
really add many locales "by mistake", so there is no real need
to delete a lot of locales at once.
