Executing client.fetch immediately after client.connect will encounter error.

[nodegin]

This issue just for logging.

const client = new Client(...}
await client.connect()
await client.fetch({
  '@type': 'createPrivateChat',
  'user_id': 1234,
})

Error

(node:7969) UnhandledPromiseRejectionWarning: Error: {"@type":"error","code":6,"message":"Chat info not found"}

Resolved in version 1.3 by adding short delay.
