Fix Sentry "Unsupported media type 'application/json, application/jso…

…n' in request" (#224)

* sentry: do not send Content-Type: application/json twice

The header is already set by called Httpie library. Calling ::header just adds a new header, does not do any replace.

Sentry does not recognize the request when we send the headers twice and fails with error:
```
  [RuntimeException] on [factcool-www3.superhosting.cz]
  Unable to create a release: Array
  (
  [detail] => Unsupported media type 'application/json, application/json' in request.
  )
```

* changelog: update
