Feat/producers desktop link

Desktop Version link at the bottom of account pages directs to the correct url.

Added the first e2e tests to verify the correct links.

This is definitely a hack, for a couple of reasons. First, there's not a uniform way to address accounts. We can't wait until the state has loaded or else our analytics get all messed up, so I do it in this middle ground by adding an account-specific translation as part of the state resolution. It's ugly, but it's the only thing I could think of that will do what we need it to. Thankfully, once we run the dedupe we will be able to take the hack out.

The other reason this is a hack is that by running our e2e tests on this repo, we're having to rely on production data for the sake of our tests and slowing them down significantly - up from ~ 3 minutes to ~ 7 minutes because we need to download and unpack the sauce connect package and start a tunnel. Obviously, this needs to change.

I'm using the half-way pretty urls because it's the only way I can avoid making a second request for individual accounts so I can get their user id. I know that we generally shy away from using them on v3 internally, but I thought the tradeoff was worth it here.

The gulpfile is starting to get a little long in the tooth, will likely need some love someday soon.
