Fix model_to_dot() for Sequential models
Fix model_to_dot() for Sequential models

The model_to_dot() function does not display the input layer of Sequential models correctly. See https://github.com/keras-team/keras/issues/10638
This fix seems to have been applied already in keras-team/keras, but not in tf.keras.
