The LDAP tab is no longer a button, but is now a link. Update the QA page

https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/21386 re-introduced

(e.g. spec/features/usage_stats_consent_spec.rb), then this spec will
fail. To work around this problem, we enable the usage ping explicitly
in the setup phase.
