build fail with --use_prebuilt_tensorflow

[cepera]

when you're building the bridge with --use_prebuilt_tensorflow, the build fails like this:

...
adding 'ngraph_tensorflow_bridge-0.12.0rc4.dist-info/top_level.txt'

Exception: Error running command: cp -r .../ngraph_20190409/build_cmake/tensorflow/tensorflow/python .../ngraph_20190409/build_cmake/artifacts/tensorflow

this piece of code should take --use_prebuilt_tensorflow into attention:

    # Copy the TensorFlow Python code tree to artifacts directory so that they can
    # be used for running TensorFlow Python unit tests
    command_executor([
        'cp', '-r', build_dir_abs + '/tensorflow/tensorflow/python',
        os.path.join(artifacts_location, "tensorflow")
    ])

Hi @cepera - thanks for pointing this out. Could you please try this fix? https://github.com/NervanaSystems/ngraph-tf/commit/1243a156afbd3c437516c80ca61738c5e1809caa

We will make a release soon with this fix included.
