- Send empty `TagPacket` and `CapturePacket` on new connections, to reset old data back that other players might still have in their puppet from an
earlier connection.
- Cache and send `CostumePacket`, `CapturePacket`, `TagPacket`, `GamePacket` and `PlayerPacket` to (re-)connecting players.
- Clear Metadata cache for existing clients that connect fresh (after a game restart).
Make and use a copy of the RemoteEndPoint at the start of the HandleSocket method.
Because in some cases when the socket is disposed, the RemoteEndPoint inside of it is cleared and isn't available for the following disconnect log entries.
Also: port scanners on the internet don't introduce themselves with a name and ID.
(cherry picked from commit 2f4cd0509a)
Currently when a client connects that is already there,
the old socket is closed, and the code tries to reuse the existing client object by exchanging its socket.
Reusing the same client object and just changing its socket does cause issues though with copies of the client in other threads.
In the situations that I could reproduce, it always disconnected both sockets, the old one and then the new one.
Instead I make a copy of the client object, use the new socket, remove the old object and add the new object to the collection.

Otherwise port scans, banned players or clients failing to initialize correctly,
will cause the server to send unnecessary packets to all connected clients.
They currently are informed about a disconnect for a client that hasn't even connected correctly.
