Title: Naive Bayes: Fix the missing value in the result

Jira MADlib-523

When the test set has values that are in the training set, we use the
Laplace smoothing to avoid a NULL output.

Extra changes:
The computation code is re-used in create_classification_function;
Documentation is changed to reflect the fix;
Useless notices and warnings during computation are removed
