v2 completely broke several connections to single redis

[a-parser]

Just abstract example:

(async f1() {
  const client1 = asyncRedis.createClient();
  await client1.blpop("some", 0);
})()

(async f2() {
  const client2 = asyncRedis.createClient();
  await client2.lpush("some", 42); 
})()

f2's lpush will never be called as client1 and client2 share same connection due to new implementation

duplicated of #60 :p

an workaround:

(async f1() {
  const client1 = asyncRedis.createClient({ _id: 1 });
  await client1.blpop("some", 0);
})()

(async f2() {
  const client2 = asyncRedis.createClient({ _id: 2 });
  await client2.lpush("some", 42); 
})()

you must pass different options for each client.
