[now-cli] upgrading to 16.3.0 breaks the routes

Summary

I’m hosting a static build of my CRA bootstrapped app to Zeit. After upgrading to 16.3.0, my route redirection to root file stopped working. I was using now.json.routes to redirect all my dynamic routes to index.html file for frontend route handling. I am getting 404 errors while accessing routes other than index. Reverting back to 16.2.0 seams to fix this issue.

My now.json file

{
  "name": "app-name",
  "routes": [
    { "src": "/static/(.*)", "dest": "/static/$1" },
    { "src": "/(.*\\.(js|json|png|jpg|ico|txt))", "dest": "/$1" },
    { "src": "/(.*)", "dest": "/" }
  ]
}

Steps to reproduce

Any SPA which is statically hosted with above routes configuration should reproduce the issue when deployed with now-cli@16.3.0.
