We need to keep the email lookup as we want to fall back to displaying
the gravatar result for a given email if the user does not exist.

Whenever we already deal with a User object, let's use the more specific
method avatar_icon_for_user.

The refs hash is used to determine what branches and tags have a commit
as head in the network graph. The previous implementation depended on
Rugged#references. The problem with this implementation was that it
depended on rugged, but also that it iterated over all references and
thus loading more data than needed if for example the project uses CI/CD
environments, Pipelines, or Merge Requests.

Given only refs are checked the network cares about the GraphHelper#refs
method has no need to reject those, simplifying the method.
