refactor(breadcrumb): make title null and undefined causes the same b…

[Asanio06]

When the title of an item is set to undefined, the item is not taken into account. Unfortunately the behaviour is not the same when the title is set to null. I use React 17 and when I don't want to display anything with a component, I return a null element to make it a valid JSX element.
