propose-update does not find release tarball in dist-git with --dist-git-path
I'm currently trying to release the new [cockpit-podman 6](https://github.com/cockpit-project/cockpit-podman/releases/tag/6) with packit instead of cockpituous. This time, the upstream branch and release includes the [packit configuration](https://github.com/cockpit-project/cockpit-podman/blob/master/packit.yaml), so no --local-content.

I'm trying to run propose- update in a checkout of the upstream branch (not completely clean, as I built the release tarball in that before). I use `--dist-git-path` to work around issue #421. It seems to download the new release tarball from github just fine, but it seems to place it in the wrong directory:
```
$ PYTHONPATH=~/tmp/packit/ python3 -m packit.cli.packit_base propose-update --no-pr --dist-git-path=/tmp/cockpit-podman
Input is a directory: /home/martin/upstream/cockpit-podman

And indeed /tmp/cockpit-podman/ is completely unaltered, no new tarball, changes, or commits. /tmp/tmpyyatb17l is gone.

This is packit master from today, 5c521f763.
