If the address is `""` then an available address is automatically
picked.
```
// Network#allocate_tcp_port
if listen_address.is_empty() {
// If listen address is empty, find us a port iteratively
let port = self.find_available_tcp_port(5150)?;
let ip_addrs = available_unspecified_addresses();
Ok((port, ip_addrs))
} else {
// ...
}
```
Clippy also informed us that we can drop some of the clone calls.
