3ce1bca670 Prevent crash when attempting to create training data without responses. 
This is at least useful when using an SVM one-class linear classifier, so there are valid use cases.

40b870704e add 2 extra methods to ml::TrainData (#7169) 
* expose 2 extra methods from ml::TrainData: getNames() and getVarSymbolFlags(). The first one returns text labels from CSV (if the data has been loaded from CSV); the second one returns a matrix of boolean values; its n-th element is 1 iff the corresponding column in the CSV uses symbolic names, not numbers.

* check that the dynamic_cast succeeds
