UI Bug For _('Audit Events') in sidebar

This translation is written literally in the UI:

Screen_Shot_2018-06-22_at_11.22.02_am

The problem is caused by https://gitlab.com/gitlab-org/gitlab-ee/blob/master/ee/app/views/projects/sidebar/_settings_audit_events.html.haml#L5

This line needs to be:

%span= _('Audit Events')
