QtAsyncio: Improve logging when an Exception occurs in a task
When an exception occurs in a task, the logging is not helpful since it prints out nothing specific about the error that occurred. Catching the traceback and printing it out with the task in which it happened brings a lot of details to resolve the exception faster.
Task-number: PYSIDE-3001
Pick-to: 6.8
