Create user token API allows creating tokens with the same name

[koaps]

Posting to the user token API (/users/:username/tokens) endpoint multiple times with the same required name creates multiple tokens.

for i in {1..5}; do curl -X POST -H "content-type: application/json" -d '{"name":"test_api_token"}' http://builder:builder@127.0.0.1:10080/api/v1/users/builder/tokens -s | jq .sha1; done


curl http://builder:builder@127.0.0.1:10080/api/v1/users/builder/tokens -s | jq .

[
  {
    "name": "test_api_token",
    "sha1": "7f5a82226a2b01abbf60e648a7553d98879be5f5"
  },
  {
    "name": "test_api_token",
    "sha1": "e617c6a60b31695cd73d5b93b257b540bfaefe1b"
  },
  {
    "name": "test_api_token",
    "sha1": "12f79d7e61945dd6959701e7d0877b68819c7611"
  },
  {
    "name": "test_api_token",
    "sha1": "b7bf07c5341e61342bcc1068b34f5fe75d5a885a"
  },
  {
    "name": "test_api_token",
    "sha1": "f40728c529c01e236bb72a8c2da4cbbab32fa9bf"
  }
]

I would think this should throw a HTTP/1.1 422 Unprocessable Entity error like the repos do

{"message":"repository already exists [uname: builder, name: builder]","url":"https://github.com/gogs/docs-api"}
