The `this` repo is skipped in the test for the `for-all-repos` command.
Adapt to checking for KAS_REPO_URL being empty instead of comparing the
KAS_REPO_NAME. This way the test will fail if the implementation
diverges from the documentation:
> KAS_REPO_URL: The URL from which this repository was cloned, or an
> empty string if no remote URL was given in the config file.
