Bug: cgit shows empty pages, when viewing Tag-Only-Repo

[Björn Lässig]

Hi,
 I use repositories for holding some tags.
Unfortunately cgit shows only

  <red>Repository seems to be empty</red>

I looked into the code and saw the problem, but i have not the insight
to fix this.

one (small) example for the Problem is:

https://git.pengutronix.de/cgit/ukl/distrokit/refs/

git ls-remote https://git.pengutronix.de/git/ukl/distrokit/
shows a handful of refs.

Thanks
