Nicolas Werner 906f8c3161 fix: type error in emote pack list in rooms with only non-default packs
If a room has emote packs, but none of them have an empty state key, we
insert 'null' to also add a default pack people can easily edit.
However, in that case we initialized the Map<String, Event?> variable
with a Map<String, Event>. As such assigning null will throw. Converting
manually with Map.of fixes that.
