72832bcbc4 Fix pinger be removed by not found. 
heatmap will be broken in every refeshPeriod,
I found pinger is be deleted because of exists check faild.

updatePingers will check if a pod still exist or a new one,
and update pingers in every refreshPeriod.

the function exists failed to check pod exist, so fix it.
