	 * vB5 sets userlist.type = 'ignore', userlist.friend = 'denied'
	 * to equate a deny so we must update these bogus records.
	 * Update userlist.type = 'follow', userlist.friend = 'denied' to
	 * userlist.type = 'ignore', userlist.friend = 'denied'
	 *
	 * VBV-11987: In previous versions, the state "type=buddy,friend=denied" was when you sent
	 * a friend request to someone and they denied it. It was shown to you as still pending.
	 * In vB5, if your follow request is denied, the state is "type=follow,friend=pending", so
	 * we should change "type=follow,friend=denied" (buddy has been changed to follow) to
	 * "type=follow,friend=pending" instead of trying to convert it into an ignore user record
	 * when it was never intended to be an ignore. Trying to convert it to an ignore record
	 * is the source of the duplicate key error, since you could have both a friend request
	 * to someone that they have denied (type=follow,friend=denied) and you could ignore
	 * (type=ignore) that same user. As for sites that successfully ran this step, there is no
	 * way to reliably detect the incorrect ignore records and reverse them, since they are
	 * marked the same "type=ignore,friend=denied" as vB5 currently marks them.
