After a Live Merge, the task in the Tasks pane is not marked as finished

Issue

• A Live Merge (snapshot deletion) was stuck and never completed.

• The task in the Tasks pane in the RHEV Admin Portal still showed it was in progress (it has the hourglass icon next to it).

• The Event Log however showed that it had completed, but it displayed it twice, once when it started and one later on;

 Disk 'disk-2' from Snapshot(s) 'snapshot-1' of VM 'VM-A' deletion has been completed (User: abc@x.y.z.com).
