Fix skip_repo parameter being ignored when destroying a namespace

When destroying a namespace, the `skip_repo` parameter is supposed
to prevent the repository directory from being destroyed and allow
the namespace after_destroy hook to run. If the namespace fails
to be deleted for some reason, we could be left with repositories
that are deleted with existing projects.
