Proxetta can't handle generic array as return value.

[tlxtellef]

Jodd version: 3.8.6
Java version: Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
OS: macOS Sierra 10.12.5

How to reproduce:

package jodd.proxetta;

import jodd.proxetta.advice.DelegateAdvice;
import jodd.proxetta.impl.ProxyProxetta;
import jodd.proxetta.impl.ProxyProxettaBuilder;
import org.junit.Test;

public class GenericsArrayTest {

    public static class Foo<Stuff> {
        public Stuff[] getArray() {
            return (Stuff[]) new Object[0];
        }

        public <Thingy> Thingy[] getArrayStatic() {
            return (Thingy[]) new Object[0];
        }
    }

    @Test
    public void testClassesWithGenericArraysAsReturnValueProxy() {
        try {
            ProxyAspect aspect = new ProxyAspect(DelegateAdvice.class);
            ProxyProxetta proxetta = ProxyProxetta.withAspects(aspect);
            ProxyProxettaBuilder builder = proxetta.builder(Foo.class);
            builder.newInstance();
        } catch (Exception e) {
            throw new AssertionError(e);
        }
    }
}

Result:

It will complain about "Thingy" instead if the first method is removed.

@tttellef thanx for notifying. Just wanted to let you know I started working on it.

The fix should not be too hard, but I want to write some testcases as many things are going on
