Calling the exception() method when future is in the cancelled state is causing a CancelledError. we should check the cancelled state first and call f.exception() only if it's not cancelled.

Could you please add a test?

Also #2392 looks a different solution of the same issue, like they choose to always pass an exception

i've looked into the issue.
It's good code, but I have a slightly different opinion.
I don't report canceledError as an error in the span because there is a subject that did the cancel, and the coroutine follows the same strategy.

        # CancelledError is raised when a coroutine is cancelled
        # before it has a chance to run. We don't want to record
        # this as an error.
