retry_strategy doesn't reset after flushing the error

• Version: node_redis 2.6.5, redis 3.2.7
• Platform: Node.js 7.5.0 on Mac OS 10.12.3
• Description:

I'm using the following code

const redis = require('redis');

const client = redis.createClient({
  url: 'redis://localhost:6379',
  retry_strategy: options => new Error('Fail')
});

setInterval(() => client.incr('some-key', console.log), 5000);

running against a local redis (docker run --rm -p 6379:6379 redis)

After I see the first output, I kill the redis to simulate disconnect. When I've seen the error come in I restart the redis. The connection doesn't come up again. I would expect that after flushing the error to the offline handlers, the client would try to reconnect on the next command. instead it stays in closed state. Also it's returning with AbortError instead of new Error('Fail').

Run the supplied Node.js reproduction with redis.createClient, retry_strategy, client.incr, and a Redis restart. Trace the reconnect and offline-handler behavior after the first disconnect, checking why the client remains closed and returns AbortError instead of the configured Error('Fail'); done means the client reconnects on a later command with the expected error behavior.
