Logistic Regression: Ignore cases with missing dependent variables.

Prior to this change, cases with missing values in the predictor
variables were ignored, but cases with missing values only in the
dependent variable would provoke an error.  Subsequent to this change
such cases are also ignored.  This seems to be the behaviour of other
software, despite what their documentation may suggest.
