fix(code-owners): put a user in the context for group resolution. r/5256

We need a user in the context when we ask the groups backend to look up
groups by name, so for now if we don't have a _real_ user in the context
(such as during change indexing), then populate the context with the
anonymous user just for the duration of the groups backend calls.
