Handle emtpy object in security array

[gui-camargo]

Describe the bug
The handle (None) that was implemented in fix #1678, no longer works correctly.
I believe this was caused by feature #2022.

Expanded:

Expected behavior
Show the text "None" (or any other text) when there's an empty security object.

Minimal reproducible OpenAPI snippet(if possible)

  /v1/merchant:
    get:
      summary: "Get information of a Merchant"
      security:
        - {}
        - apiKey: []

I am also seeing this. It makes the API docs more confusing. Hoping someone can fix this! 🙂
