Creating peer without network connection crashes an app

[VladSalat666]

Hi

If there is no network connection, folowing code crashes an app:

let peer = peerJs(id, {
	host: 'example.com',
	port: 443,
	debug: 0,
	secure: true,
	pingInterval: 5000,
	config: {
		iceServers: [
			{ urls: ['stun:stun.l.example.com:1245'] },
			{ urls: ['turn:user@12.34.56.78:1234'], username: 'user', credential: 'root' }
		]
	}
});

Even trycatch can't handle this error...

events.js:187
      throw er; // Unhandled 'error' event
      ^

Error: getaddrinfo ENOTFOUND example.com
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:60:26)

}

host replaced by example.com, with right host and network connection all works good
