DL: Check for NULL in class_values for fit_multiple_model

For, already one-hot encoded data(y), the class_values is set to NULL by
the input preprocessor. Prior to this commit, the function
`madlib_keras_fit_multiple_model()`, assumed the class_values will
always be present and failed incase of class_values being passed in as
NULL. This commit fixes this issue and adds a dev-check test for the
same.

Also, this commit updates the `validation_table` to be set to NULL instead
of None in the summary table
