Allow commit status popup on /pulls page

The /pulls page doesn't contain a "repository" element, so the early-out here was preventing the commit status popup hook from working. However, the only thing the .repository element is being used for here is determining whether the popup should be on the right or on the left, so we don't actually need the element to exist for the hook to work.

Pull request go-gitea#19375 allows the statuses on /pulls pages to appear clickable, but this commit is required to make the popup actually work there.
