Updating `TaskDetails`-object makes `Task`-object undeleteable.

Problem:

task=bucket.create_task("testtask")
taskdetails=task.get_details()
taskdetails.update(description="testdescription")
task.delete()

results in:

Traceback (most recent call last):

Workaround Refresh the task object without actually changing it.

task.update(title=task.title)
task.delete()

It would be nice if updating the TaskDetails-object also would refresh the Task-object.

PR are very welcome. If you have the time and know how to properly solve this I would be grateful if you submit a PR.

Thank

@alejcas I can confirm this error occurs.

I think the only way the parent etag could be updated is by adding a call to re-retrieve the task. This is not necessarily what all users would need, and can be handled in the calling code when needed anyway. I'd suggest to leave the code as is.

Ok, I'll close this then. Thanks
