[GROOVY-9857] Immutable generates invalid super constructor call

Description

The transforms invoked by @Immutable generate constructor code that unconditionally makes a call to super() even when the superclass has no default constructor.

@TupleConstructor(defaults = false)
abstract class AbstractClass {
    String a
}

@Immutable
class ImmutableSubclass extends AbstractClass {
    String i
}

Compiling this pair produces invokespecial AbstractClass.<init>(), which does not exist. This should at a minimum produce a compile-time error.
