Failed Jobs tab could group traces by stage and sort to show jobs with traces first.
What
On the new Failed Jobs tab from https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/10719, we should group jobs by stage. Since we are only showing 10 build traces, we could also sort to have builds with traces first.
Why
Keep failures in a logical order and ensure that limit is 10 build traces rather than 10 jobs which may/may-not have traces.
