Orion incorrectly escapes quotes in headers to WebExtensions

Steps to reproduce:

1. Have a WebExtension use the webRequest API to intercept requests.
2. Send a request with a header with the value containing a quote, for example
   fetch("myserver.com", {headers: {"Hello": JSON.stringify("World") }})
   Expected behavior:
   In Chrome, the extension recieves the header as expected, however in Orion, all " quotes are replaced with \".
