Brought nearest mean response tests in line with new framework. Had to make very small change to minimal_dataframe_lookup function in conftest as NMI transformer requires a dataframe where columns have some nans in order to pass generic tests.
Also added in minor error handling step in the imputer script itself, as the default value for the y parameter is None which falls over immediately as one of the first steps in fit is 'y.isna()' and None has no 'isna' attribute.
Also overwrote 'test_fit_not_changing_data' in generic tests in the NMI specific tests scripts as base test for 'test_fit_not_changing_data' is set up without a y value being called in fit, which works fine for other transformers but not for NMI.
