Ref: https://issues.redhat.com/browse/MTV-1310

Issue: Disk transfer tasks aren't completed although the migration is successful

The individual tasks of the pipeline step do not finish, although the pipeline step is completed

As a workaround, if the UI see that the step is finished, but some individual task did not finish, override the individual task data, and show it as if it is finished.
