The error results by a false tree length value in the tree. The linear interpreter creates an array based on this value, but does not fill every entry with an instruction, which leads to the NullReferenceInstruction during interpretation.

r10273: Adapted the SymbolicClassificationSolutionImpactValuesCalculator to manipulate the cloned tree instead of using the cloner itself for the node exchange. Hence, the tree lenght value is recalculated and matches the current tree lenght.
