Fix TCPShield compat by using raw address for sessions

TCPShield overwrites the IP address during connection. ProtocolLib
doesn't notice this change, because it uses the end-to-end connection
which is the proxy IP. This causes getAddress calls during Spigot play
state and ProtocolLib auth state not match and then have conflicting
session ids.

A solution is also to hold onto the temporary player object. However
since we don't get a notification for a disconnect, holding it will
prevent to get GCed until the timeout occurs (1 minute).

Fixes #595
