fix(test): defer redis-5 require so DC subscriber registers before connect

node-redis eagerly creates native TracingChannels on require(), and
the DC subscriber is deferred via Promise.resolve().then(). Moving
the require inside run() after a microtick ensures the subscriber
is registered before the connect event fires.
