added a try...except to handle the 400 from server side
- the server code throws a Bad Request when updating superevent attributes which are possibly caused due to numerical precision (see #57 (closed) and comments therein)
- First cut solution to #57 (closed)
- Added a unittest to test_task_superevents to show the logic of the code does not fail when uploading the same event twice (or multiple times)
