Wildcard server only sends interactions to one connected client, instead of all of them

[denandz]

Interactsh version:

1.2.4

Current Behavior:

When running an interactsh server with the -wc option, all interactions are logged and sent to a client regardless of the subdomain. If two clients are connected to the interactsh server, only one of them will receive the interaction data.

Expected Behavior:

All clients connected to a server run with -wc wildcard option enabled should see all interactions with that server.

Steps To Reproduce:

1 - run an interactsh server with -wc
2 - connect to the interactsh server with two different clients (eg: two different terminal windows)
3 - trigger an interaction
4 - notice that only one client recieves the interaction data.

The following screenshot shows the example with two clients, and only one receiving the data.

curl --resolve foo.testlab.local:80:<test interactserver ip> http://foo.testlab.local/FINDME was used to trigger the interaction.

Anything else:

Similar to #1135 - this functionality needs to send all interactions to all connected clients to support a team of security testers sharing infrastructure or working on the same target.
