HPCC-8755 Fix Auto Refresh on ECL WU Details page

When ECL WU Details page is opened for a running WU, the page should
be auto-refreshed itself every x minutes. That function was broken
since the call to the auto-refresh function was removed by mistake.
This fix adds the call back when the page is loaded.
