Critical issue: cote does not respond to sequential queries with delay

Hello. I ran into the following issue: when I send query to same responder with some delay (say, 2 second), only first query get response. Here is code:

import cote from 'cote'

const delay = (msecs: number) => new Promise((resolve: () => void) => setTimeout(resolve, msecs))
const onResponse = (err: any, res: any) => {
  console.log('result:', res)
  console.log('error:', err)
}

const responder = new cote.Responder({ name: 'auth' })

responder.on('request', (req: any, cb: any) => {
  console.log('received request: ', req)
  cb(null, 'response')
})

async function main() {
  const requester = new cote.Requester({ name: 'req' })

  requester.send({ type: 'request', data: 'fooBar' }, onResponse)

  await delay(2000)
  requester.send({ type: 'request', data: 'fooBar' }, onResponse)

  await delay(2000)
  requester.send({ type: 'request', data: 'fooBar' }, onResponse)
}

main()

Only first query gets response using the code above.

OS: Windows 10 Node: v12.2.0 Cote: 0.20.0

I also tried to turn off windows firewall, no effect.

UPD1: I tried to launch time service example (from top of cote documentation), and if I launch time client.js repeatedly, I get answer only for first time after time_service.js start

UPD2: I noticed that example above will work if I will stop few other cote services. They have nothing common with example above, not a service name nor query type.

I updated the README to reflect this nature.
