Our user update method(s) might miss some parts

[Lulalaby]

as ref:

		usr = this.UserCache.AddOrUpdate(usr.Id, usr, (id, old) =>
		{
			old.Username = usr.Username;
			old.Discriminator = usr.Discriminator; // obsolete
			old.GlobalName = usr.GlobalName;
			old.AvatarHash = usr.AvatarHash;
			old.BannerHash = usr.BannerHash;
			old.BannerColorInternal = usr.BannerColorInternal;
			old.AvatarDecorationData = usr.AvatarDecorationData;
			old.Collectibles = usr.Collectibles;
			old.ThemeColorsInternal = usr.ThemeColorsInternal;
			old.PrimaryGuild = usr.PrimaryGuild;
			old.DisplayNameStyles = usr.DisplayNameStyles;
			old.Nameplate = usr.Nameplate;
			return old;
		});

i think thats all rn

Currently missing (at least):

• Banner color
• Avatar decoration data
• Collectibles
• Theme colors
• Display name style
• Nameplate

I don't think we want this for 2.7.1, the latter is overdue already
