TranslationModelComparator bug

[jwest86]

Change:
List<ConcreteRule<IString,String>> dynRules = dynTM.getRules(source, null, sourceId, scorer);
List<ConcreteRule<IString,String>> compRules = compiledTM.getRules(source, null, sourceId, scorerComp);
To:
List<ConcreteRule<IString,String>> dynRulesList = dynTM.getRules(source, null, sourceId, scorer);
List<ConcreteRule<IString,String>> compRulesList = compiledTM.getRules(source, null, sourceId, scorerComp);
RuleGrid<IString,String> dynRules = new RuleGrid<IString,String>(dynRulesList, source);
RuleGrid<IString,String> compRules = new RuleGrid<IString,String>(compRulesList, source);
