  Log Message:
  -----------
  Fix task result status retrieval (MID-6721)

When getting task object in a standard way (i.e. without explicitly
asking for task.result) the result status was cleared. This is now
fixed.

Other changes:
- Structured progress is now updated from in-memory task (if found).
- Marked some parts of OperationResultType as optional, to allow
partially defined objects.
- Marked UriStack (for tasks) as deprecated.
- Fixed NPE when parsing operation results without tokens.
