testPort gets called with 65536

[fryorcraken]

Somehow, the library tests an invalid port:

Uncaught RangeError [ERR_SOCKET_BAD_PORT]: options.port should be >= 0 and < 65536. Received type number (65536).

I called the library with a random port as some calls are done in parallel and I had conflict issues in the past:

    const startPort = Math.floor(Math.random() * (65535 - 1025) + 1025);

    const ports: number[] = await new Promise((resolve, reject) => {
      portfinder.getPorts(4, { port: startPort }, (err, ports) => {
        if (err) reject(err);
        resolve(ports);
      });
    });

I was expecting this error to be thrown instead:

node-portfinder/lib/portfinder.js

Line 58 in 123a06f

return callback(new Error('No open ports available'));
