Merge bitcoin/bitcoin#29393: i2p: log connection was refused due to arbitrary port

5b358cdd1a5f5d2fe87a9e41c638996eab2e2796 i2p: log connection was refused due to arbitrary port (brunoerg)

Pull request description:

  For I2P, we do not try to connect if port is != 0. However, we do not have anything that indicates it or any error when trying to connect with port != 0. This PR adds a log for it. Also, it improves the functional test. With this log we can ensure the reason we won't connect is the port, in the current test, we cannot ensure it.
