Fix username and ID not logging in production_json.log for Git activitysh-fix-username-logging

Devise sets `current_user`, but not all controllers authenticate users by
session tokens. Try to use the controller-defined `authenticated_user` if
`current_user` is not available.

Closes gitlab-org/gitlab-ee#3611
