## Observation
We got these warnings on o3:
```
[2024-08-05T08:35:30.423569Z] [warn] [pid:24853] warning: refname '1b53ef6634d0d8e838c9726d42877bfd4dd13541' is ambiguous.
Git normally never creates a ref that ends with 40 hex characters
because it will be ignored when you just specify 40-hex. These refs
may be created by mistake. For example,
git switch -c $br $(git rev-parse ...)
where "$br" is somehow empty and a 40-hex ref is created. Please
examine these refs and maybe delete them. Turn this message off by
running "git config advice.objectNameWarning false"
fatal: Invalid revision range 1b53ef6634d0d8e838c9726d42877bfd4dd13541..6f8ff6e139e08ebeca34a51aa51143921653b586

Here is a corresponding section of /var/log/openqa with the actual command:

Running that command

I quickly looked up which job has that git ref:
https://openqa.opensuse.org/tests/4380936
But there are many more with `CASEDIR: https://github.com/os-autoinst/os-autoinst-distri-opensuse.git#1b53ef6634d0d8e838c9726d42877bfd4dd13541`
