Change jobExecutions status to much uiStatus from the backend

Purpose:

Now jobExecutions on UI are distinguishing by the status field in the model which contain implementation detail status from the backend that does not fully match the purpose of the UI. For example, one uiStatus can match several entities with different status fields. For that reason backend developers introduced uiStatus field. In the scope of this story, the replacement of the statuses should be done. From status to uiStatus.
