The `propose-downstream` seems to not execute `post-upstream-clone` action
Hi everyone. It seems that the `packit propose-downstream <project_url>` doesn't execute the `post-upstream-clone` action. We have this action on Anaconda [.packit.yml](https://github.com/rhinstaller/anaconda/blob/master/.packit.yml#L5) to generate `anaconda.spec` from `anaconda.spec.in`, however, it seems that this action is not executed because we are getting fail that `anaconda.spec` doesn't exists.

Steps to reproduce:
1. Call `packit -d propose-downstream https://github.com/rhinstaller/anaconda`.

```
$ packit -d propose-downstream https://github.com/rhinstaller/anaconda
