hide-hostname option adds a slash - openapi 3.0

[codyaray]

Either a regression or a miss on the fix for #201. My guess is that this may be specific to openapi 3.0, as that's what I'm using and 3.0 wasn't yet supported when #201 was closed.

I'm seeing this using redoc-cli@0.9.12 (which uses redoc 2.0.0-rc40) with an openapi 3.0 spec with a single server.

Reproduction steps:

---
openapi: 3.0.0
info:
  title: Test API
  version: 0.0.1

servers:
  - url: https://api.example.com

paths:
  /some/example/path:
    get:
      responses:
        '204':
          description: No Content.

Then bundle it

$ redoc-cli --version
0.9.12

$ redoc-cli bundle openapi.yaml --options.hideHostname
$ open redoc-static.html

This is what you see when you click the dropdown:

Quick investigation looks like it was independently re-introduced here:

redoc/src/components/Endpoint/Endpoint.tsx

Line 76 in 4db5bc4

{hideHostname || options.hideHostname

Note that the pathname defaults to "/" instead of "" when its empty, causing this issue again. Validation:

Thanks for the bug report.

This will be released with the new rc later this week.
