When converting a tflite model to an onnx ModelProto using from_tflite() function, if the output_names argument is not specified, it defaults to an empty list instead of None.
However, in the tf2onnx.tflite_utils.graphs_from_tflite function, if the output_names argument is not None, the output names retrieved automatically by the tf2onnx.tflite_utils.parse_tflite_graph function are overwritten, resulting in a ModelProto with no output which causes a bug.
So the function should not change None to an empty list for both input_names and output_names arguments. This PR fixes this problem. Add related tests as well.
