Incorrect loading of no_avatar
Overview
We use the no_avatar for the default avatar in https://gitlab.com/gitlab-org/gitlab-ce/blob/master/app/helpers/application_helper.rb#L91 - also in gon https://gitlab.com/gitlab-org/gitlab-ce/blob/master/lib/gitlab/gon_helper.rb#L5
On GitLab.com when loading no_avatar we default to https://gitlab.com/assets/no_avatar.png (which does not exist) - Specifically for approvals
