ClassificationPerformanceMeasures are not recalculated when the data changes

Description

After the data of a classification solution is changed all classification results have to be recalculated. This is the case for the standard performance measures (accuracy, ...), but the classification performance measures depending on the positive class are only updated when there was no error during their calculation.

When new data is loaded all available samples belong to the test partition, hence the performance measures for the training partition cannot be calculated and are not reset, displaying the old, out-dated values.
