[MC-157426] Command outputs which should be sorted don't get sorted

Steps to reproduce:

Run the commands

/tag @s add a
/tag @s add b
/tag @s add p
/tag @s add q
/tag @s list

The feedback is

Player has 4 tags: p, a, q, b

but it should be ordered alphabetically

Player has 4 tags: a, b, p, q

Other affected commands: /scoreboard players list and /team list <team>

Code analysis (official mappings)

public static Component formatAndSortList(Collection in, Function formatter) {
    if (in.isEmpty()) {
        return new TextComponent("");
    } else if (in.size() == 1) {
        return (Component)formatter.apply(in.iterator().next());
    } else {
        ArrayList sorted = Lists.newArrayList(in);
        sorted.sort(Comparable::compareTo);
        return formatList(in, formatter);
    }
}

The method formatAndSortList in ComponentUtils ignores the sorting result.
