Sanitize repo name when including in a layer title

These titles were previously including the filename as {org}/{repo}_{version} which means when clients download the layer they think it needs to be unwrapped into a folder called {org}.
This is not what we want, so we should instead rename the file as {org}-{repo}_{version}. e.g. from myorg/myrepo_myversion.zip to myorg-myrepo_myversion.zip
