[UI] Internal error during cluster deletion

[Andrew Lazarev]

I had 3 clusters I wanted to delete. I marked all three of them and clicked 'delete clusters'. After some time 'Failed to update row' message occurred on client side.

Stacktrace from horizon:

No errors on sahara side.

It looks https://github.com/openstack/horizon/blob/stable/juno/openstack_dashboard/dashboards/project/data_processing/clusters/tables.py#L83 section is missing "raise Something" instruction.
