Better error handling for expired files in `civis.io.file_to_dataframe` #336

When reading from an expired file using civis.io.file_to_dataframe, the user gets a long traceback and the following error message: ValueError: Invalid file path or buffer object type: <class 'NoneType'>. We should catch this error and return something more informative.
