Force wrapping java classes from annotation methods into KClasses

Before this change such wrapping happened only during coercion,
i.e. when a call-site expected a KClass instance.

But when call-site expects Any, for example, no wrapping happened,
and raw j.l.Class instance was left on stack.

The solution is to put wrapping code closer to generation of annotation's
method call itself to guarantee that necessary wrapping will happen.
