Unable to get commit comparasion data via API when Pull Request feature is disabled

[dangjinghao]

Description

The API endpoint /repos/{owner}/{repo}/compare/{basehead} fails to return commit comparison data (in the same branch) when the "Pull Requests" feature is disabled for a repository. The request returns an error: {"errors":null,"message":"Can't read pulls or can't read UnitTypeCode","url":"https://xxx.com/api/swagger"}.

However, commit comparison through the web interface continues to work normally.

Test it with this command:

curl -X 'GET' 'https://demo.gitea.com/api/v1/repos/dangjinghao/test-diff/compare/5b20aef62d...main' -H 'accept: application/json'

web: https://demo.gitea.com/dangjinghao/test-diff/compare/5b20aef62d...main
