Defining responses for additionalInterfaces doesn't work
The metaClass used in JavaMocks of Groovy classes did not contain the methods of additionalInterfaces, so the fix is to change the MetaClass, if we are a GroovyObject and have additionalInterfaces to the mocked MetaClass. It is not the best solution, because we now use the MetaClass of the Mock, which also contains methods and interfaces of Spock internal, but there is currently no class implementing mockType + additionalInterfaces. This would be a bigger rework. Moved the metaClass field down to BaseMockInterceptor to use it in both cases: GroovyMockInterceptor and JavaMockInterceptor The second fix is for the JavaMock of a Java class with additionalInterfaces. Previously the mockType of the Java class was used also for the methods of the additionalInterfaces, which lead to a NullPointerException. This fixes spockframework#1405
