Duplicate Accept Headers

[christianhelle]

Description
Duplicate accept headers like [Headers("Accept: application/json, application/json")] are generated when an endpoint has multiple responses with a payload. In this case, an endpoint can respond with HTTP 200 or 203 and both responses include a application/json payload in the response body

@guillaumeserale I found a case where [Headers("Accept: xxx. xxx")] was generated using duplicate values. A fix is on the way

@christianhelle looks like I missed an edge case. Good catch! 👍
