[Bug]: URL encoded space in path causes ___netlify-handler function to 502

[chrishannaby]

Steps to reproduce

For a site using v4 of the plugin if you try to navigate to the a path that contains a URL encoded space character i.e. %20 the ___netlify-handler deployed by the plugin returns a 502 error. You can see a live example of this here:

https://next-kitchensink-starter.netlify.app/hello%20world

Which returns this error:

{"errorType":"TypeError","errorMessage":"Request path contains unescaped characters","trace":["TypeError [ERR_UNESCAPED_CHARACTERS]: Request path contains unescaped characters","    at new ClientRequest (_http_client.js:147:13)","    at request (http.js:46:10)","    at /var/task/.netlify/functions-internal/___netlify-handler/bridge.js:169:19","    at new Promise (<anonymous>)","    at Bridge.launcher (/var/task/.netlify/functions-internal/___netlify-handler/bridge.js:167:12)","    at async Runtime.handler (/var/task/.netlify/functions-internal/___netlify-handler/___netlify-handler.js:123:40)"]}

Tested with @netlify/plugin-nextjs@4.0.0-beta.6
