`git obs meta list` failed to list specific branches when specified

[AdamMajer]

The bug is that specifying the --branch for this call does nothing and seems to default to the default branch. It would also be nice to have a switch (or maybe default?) to list ALL branch meta.

> git obs meta list --branch main
Branch     : main
apiurl     : https://api.opensuse.org
project    : devel:Factory:git-workflow
package    : 


> git checkout staging
Switched to branch 'staging'

> git obs meta list --branch main
ERROR: Git SCM package working copy doesn't have the following metadata set: apiurl, project
 - The package has no parent project checkout

To fix apiurl:
 - Run 'git-obs meta set --apiurl=...'

To fix project:
 - Set 'obs_project' in the matching _ObsPrj git repo, 'staging' branch, '_manifest' file
   Run 'git-obs meta pull'
 - Run 'git-obs meta set --project=...'

Check git-obs-metadata man page for more details

once the current branch has meta defined, I can list other branch's meta. If meta for current branch is undefined, it just gives me the error.

Thanks for catching this. Let me look into fixing it.
