feat: add test `should close the connection if no handshake is received`

[Totodore]

According to the socket.io protocol, a socket.io server should drop the engine.io connection if the client did not send any handshake before the connectTimeout parameter.

It also implies to set a connectTimeout parameter in the test server config that is greater than the pingInterval + pingTimeout to avoid other tests to fail.

Currently it is not tested in this test-suite and it would be nice to add it.

Awesome, thanks! I've increased the value of connectTimeout, because it would make other tests fail.

Unrelated, but do you mind if I mention socketioxide here?

[Totodore]

It would be really nice 😄, thanks a lot
