757: Fixing empty TaskError response r=curquiza a=larskristianhaga

# Pull Request

Seems like the `TaskError` object is only returning empty Strings when trying to get the error details of a task. Seems to be a missmatch between the field naming, and number of fields based on the API response. Therefor it dosent understand what to map, and only gives empty strings back.


## Related issue
None

## What does this PR do?
- It moves the `TaskError` class to the `model` package, closer to the usage in `Task` class.
  - Since its peers`TaskDetails`, and `TaskStatus` are already here.
- Updates the field in `TaskError` to match the API naming, and number of fields.
- Updates the Exception integration test to use the correct naming and import.
- Adds Integration tests to check that `TaskError` fields is not blank or null.
