RPUITask's onCancel does not respect RPOrderedTask's closeAfterFinished flag, as onSubmit does #149
Description
When the user confirms cancelling the task (showCancelConfirmationDialog), the navigator is
popped twice to close the cancel confirmation dialog and exit the task.
The task should only be exited if the closeAfterFinished is true, but is done unconditionally.
See line Navigator.of(context).pop(); // BUG <- should be called conditionally below.
Am I right, or is this the intended behavior? I am going to investigate it on my fork and will report back.

showDialog<dynamic>(
