When the input parameters of what_sites and get_info results in empty data set, the return value is a dataframe with different columns names. Instead one would expect an empty dataframe with the same columns as the normal output.
Example:
nwis.what_sites(**{'stateCd': 'ny', 'parameterCd': ['00056', '00058', '00059', '50051', '74072'], 'hasDataType': 'iv'})results in (correctly)
