The `Open` button in the PR list lacks some checks

[lng2020]

Description

Currently, the only check of this button is

gitea/routers/web/repo/issue.go

Lines 2882 to 2884 in 3c13130

	if issue.IsPull && issue.PullRequest.HasMerged {
	continue
	}

This will cause some problems such as when the head branch is deleted or the fork repo changes the visibility.

But I'm not really sure about the whole check condition. Are there any other cases that the PR should not be reopened?
