`kwargs` used to be the second argument, but it is now being interpreted
as `get_response`. Since there's no response coming it'll hang until a
timeout occurs.
Fixes
```

That occasionally occurs in the selenium tests.
this is a bit of a hack but given the lack of clarity of what
field does what on what object (info/message/description on ldda/ld/folder)
it should help with the data presentation
This was all working correctly in my test, but removes some custom logic.
It was theoretically possible for the old logic to fail if there was
no output dataset for the job.
