Task description (e.g., __repr__) should use task id, not task name

[nicelhc13]

Task name is not unique and is not descriptive. We should rename task name to task type and use task id for description.

I absolutely second this. I've made __str__ and __repr__ changes locally soo many times while debugging or profiling something. The Parla default doesn't say anything useful.

Thank you for your opinion. I will handle this task after we make some progress on our major tasks
