When having multiple projects in a session, PR short link directs to wrong link

### Describe the bug

when i have multiple projects in a session, i sometimes will create multiple PRs for each project individually. the PRs only link to the initiall project/repo i started the session in

### Affected version

_No response_

### Steps to reproduce the behavior

1. add multiple repos in your session
2. ask to create PRs for each project
3. the shortened links will only direct to the initial repo/project
- when the short link looks like this `PR #123`

### Expected behavior

I should get redirected to the correct repo/project PR

### Additional context

_No response_

通过向一个会话添加多个仓库并为每个仓库创建一个 PR 来复现该问题。跟踪 `PR #123` 短链接的处理过程，并验证每个链接解析到其 PR 所创建的仓库，而不是会话的初始仓库。
