Describe the bug you're encountering

When user selects application/edn as the Content-Type of a request body, Swagger UI incorrectly treats it as JSON.

To reproduce...

Steps to reproduce the behavior:

1. Download this example project https://github.com/metosin/reitit/tree/master/examples/pedestal-swagger
2. Run lein repl inside this folder
3. Execute (start)
4. Visit http://localhost:3000/
5. Expand the POST /math/plus endpoint
6. Set "parameter content type" to application/edn
7. Input a body like {:x 0 :y 1}
8. Press "Execute"

Expected behavior

Swagger UI simply sends the POST request. The backend can handle improperly formatted EDN data; Swagger does NOT need to validate anything.

Screenshots

Reproduce the issue using the metosin/reitit pedestal-swagger example: run lein repl, execute (start), and open the /math/plus endpoint in Swagger UI. Select application/edn and submit {:x 0 :y 1}; done means the request is sent without being treated as JSON or validated as JSON.
