Timing condition in Container.logs() - may raise DockerException rather than NoSuchContainer if container exits

[LewisGaul]

This is because the utils.stream_stdout_and_stderr() function doesn't handle the different error outputs like utils.run() does. Could we factor this logic out and use it from the stream_stdout_and_stderr() function too?

That seems like a good improvement!
