Title: don't try to connect when calling quit on disconnected client

Currently if you call `quit` on a redis connection, it'll *try* to
connect to redis before quitting. This seems weird, and can cause
issues in production environments (e.g. because of the current
implementation, `quit` can throw connection exceptions, which doesn't
seem to make sense at all)
