topic: also add topic and topic namespace caches to bundlerepository

This allows ctx.topic() and ctx.topic_namespace() actually return something
when ctx belongs to a bundle repository.

This should in theory be safe to just do because we only expose already
existing commit extras that we'd get from the repo on pull anyway.
