pr create in a non-forked repository

[fwag]

It's not possible at the moment to create a PR in a non-forked repository.
Parameters --target-owner,--target-repo are missing (the default may be the same owner/repo)

Traceback (most recent call last):

AttributeError: 'NoneType' object has no attribute 'owner'

temporary fix

        if source_repo_obj.parent_obj is None:
            target_owner = source_owner
            target_repo = source_repo
        else:
            target_owner = source_repo_obj.parent_obj.owner
            target_repo = source_repo_obj.parent_obj.repo
