Title: Unicorn preloading fixes

Two things:

- Bump the Unicorn version to current, and pin it
- Preload the app and try to preload translations when spinning up

Some cursory load testing has shown that restarting the app under this strategy doesn't make things worse, and may make things better. Either way it's more likely we'll get actual 0 downtime deploys by preloading.
