Make options.addr available

[crazymind]

Little fix to give the possibility to set the options.addr. Currently it will be overwritten by the port number.

ngrok: {
    addr: 'https://localhost:3000',
 },

If you use a ssl on localhost you need to set a url for ngrok.connect instead of the port only. Else you receive an 3004 error.

server: {
    host: 0,
    port: 3000,
    https: {
      key: fs.readFileSync(path.resolve(__dirname, 'server.key')),
      cert: fs.readFileSync(path.resolve(__dirname, 'server.crt')),
    },
  },
