Title: Switch transcript capturing to use wiredump_device; Update scrub tests to not use send

It turns out capturing transcripts is easier than what I was doing before; you can use [wiredump_device](https://github.com/Shopify/active_utils/blob/master/lib/active_utils/common/connection.rb#L104) from active_utils.
