What this PR does / why we need it

Quote from #219 (comment) :

I'm suspecting this commit grafana/grafana@6f38883.
The updateTimeRange is no longer called before issueQueries so this.range is not set until super.issueQueries is called.

Special notes for your reviewer

Does this PR introduce a user-facing change?

  concat(department,' - ',product_series,' - ',base_qgmr_version) AS metric,
  min(CASE ci_result WHEN 'FAIL' THEN 0 WHEN 'PASS' THEN 1 WHEN 'NONE' THEN 2 WHEN 'RUNNING' THEN 3 ELSE -1 END) AS "status"
