Description

If I try to create an issue via the API and I try to assign a milestone in that request it won't be set.

Request:

curl -X POST "https://try.gitea.io/api/v1/repos/JonasFranzDEV/gitea/issues" -H  "accept: application/json" -H  "Content-Type: application/json" -d "{  \"body\": \"Test\",  \"milestone\": 165,  \"title\": \"Test Milestone\"}"

Response:

  "updated_at": "2018-06-18T13:08:57Z",
  "closed_at": null,
  "due_date": null,
  "pull_request": null
}

milestone is null but should be set.

I have no issue on the release/v1.4, but I can reproduce this bug on master.
