Description

When you have many tags in a repository and you browse the tree of one of them, the commits count in the up left corner displays the commits count of the last pushed tag and not the tag you are browsing.

You can see it here : https://try.gitea.io/issuereporter224/repo

You have 5 very simple commits and 3 tags on them. If you select the last tag "vfour", it displays 4 commits so it's good. But if you select one of the 2 tags above, it will continue to display 4 commits when it should display 2 commits on the "vtwo" tag and 1 commit on the "vone" tag.

Thank a lot for all your work, i love gitea 😀

I found the problem but noticed some follow-up problems which prevent a quick PR.
