TcpConnectionSniffer drops connection data senders only when packet is received

[Razz4780]

Bug Description

TcpConnectionSniffer sends mirrored data to the clients via tokio's broadcast channels. The channel is correctly created when a new session packet is received. However, it is only removed when we receive a packet and detect that either:

1. This packet closes the connection - good.
2. All data receivers are dropped - bad. We should drop the channel as soon as all receivers are dropped, without waiting for the packet to come
