Fix the List run to get all runs

[IronPan]

We now don't assume runs always have resource reference, the sql query need to update to avoid assuming it exist. Otherwise the runs created not inside an experiment won't show up in the list run view.

Query change
Before

SELECT subq.*, 
       "[" 
       || Group_concat(r.payload, ",") 
       || "]" AS refs 
FROM   (SELECT rd.*, 
               "[" 
               || Group_concat(m.payload, ",") 
               || "]" AS metrics 
        FROM   run_details AS rd 
               LEFT JOIN run_metrics AS m 
                      ON rd.uuid = m.runuuid 
        GROUP  BY rd.uuid) AS subq 
       LEFT JOIN resource_references AS r 
              ON subq.uuid = r.resourceuuid
	   WHERE  r.resourcetype = 'Run'
GROUP  BY subq.uuid 
ORDER  BY createdatinsec ASC, 
          uuid ASC 
LIMIT  21 

After

SELECT subq.*, 
       "[" 
       || Group_concat(r.payload, ",") 
       || "]" AS refs 
FROM   (SELECT rd.*, 
               "[" 
               || Group_concat(m.payload, ",") 
               || "]" AS metrics 
        FROM   run_details AS rd 
               LEFT JOIN run_metrics AS m 
                      ON rd.uuid = m.runuuid 
        GROUP  BY rd.uuid) AS subq 
       LEFT JOIN (SELECT * 
                  FROM   resource_references 
                  WHERE  resourcetype = 'Run') AS r 
              ON subq.uuid = r.resourceuuid 
GROUP  BY subq.uuid 
ORDER  BY createdatinsec ASC, 
          uuid ASC 
LIMIT  21
