Double prefix

[fynncfchen]

Version: v4.0.0

Setup:

import redis from 'redis';
import session from 'express-session';
import connectRedis from 'connect-redis';

const RedisSessionStore = connectRedis(session);
const redisSessionClient = redis.createClient({
  host: '',
  port: '',
  password: '',
  prefix: 'sess:',
});
const redisSessionStore = new RedisSessionStore({
  client: redisSessionClient,
});

Actual Result:

sess:sess:nB9Rf0wRY-w6Ig2rvWOYhRMuusBmi90R

Expect Result:

sess:nB9Rf0wRY-w6Ig2rvWOYhRMuusBmi90R

Workaround:

import redis from 'redis';
import session from 'express-session';
import connectRedis from 'connect-redis';

const RedisSessionStore = connectRedis(session);
const redisSessionClient = redis.createClient({
  host: '',
  port: '',
  password: '',
});
const redisSessionStore = new RedisSessionStore({
  client: redisSessionClient,
  prefix: 'sess:',
});

Correct, the store always sets a prefix by default, ensuring it exists regardless how the client is set up. If a client, such as redis in your example also supports adding a prefix it will be duplicated. I will add some notes to the readme.
