Local Netlify Dev: redirects not working

[samajammin]

Hey folks! First off, thanks for building this great tool.

Bug

- What is the current behavior?

TL;DR: my redirects work on deploys but not in my local environment

I'm trying to add redirects to the site via netlify.toml:

[[redirects]]
  from = "/old-path"
  to = "/new-path"

When I run netlify dev locally, the redirect doesn't work. The URL returns a 304 code, then displays the 404 page.

I pushed this same change & opened a PR:
ethereum/ethereum-org-website#337
The redirect works in my deploy preview.

- If the current behavior is a bug, please provide the steps to reproduce.

1. Clone my branch
2. run netlify dev
3. Access the URL (http://localhost:8080/old-path)
4. The site stays on http://localhost:8080/old-path

- What is the expected behavior?
Accessing the URL http://localhost:8080/old-path should 301 redirect to http://localhost:8080/new-path

This actually works when I access the site from port 8888 instead of 8080 🎉
