An invalid task causes bitbake to exit incorrectly, firing a
CommandCompleted event rather than a CommandFailed one. This
means that clients listening for CommandFailed events are
unable to detect the build failure even though one occurred.
Passing an exception string to finishAsyncCommand when a task
fails causes the CommandFailed event to be fired correctly.
