Constructor for playerlist header and footer packet (SPacketPlayerListHeaderFooter) is missing footer parameter

Based on 1.11.2 decompiled using MCP 9.35 rc1

The bug

The constructor for the playerlist header and footer packet (SPacketPlayerListHeaderFooter) is missing a footer parameter. This is not a problem in vanilla gameplay because this packet is currently not send, but will very likely cause problems in the future.

The problem is that like this you cannot set a footer text component and therefor when the packet is sent the server tries to turn null into a JSON String which is not possible and results in the connection to the client being closed.

In 17w06a the obfuscated name of the packet class is ih.
