RandomOptionGenerator generates Option<Object> instead of actual Option<T>

[araknafobia]

As I explained in gitter https://gitter.im/j-easy/easy-random?at=5eb800d25cd4fe50a3ffea5f Optional fields generated by easy-random can not be casted to actual value of T.

You can simple do the followings to recreate the issue:

@Data
@AllArgsConstructor
@NoArgsConstructor
public class ExampleClass {
    private Optional<String> a;
    private Optional<String> b;
}

ExampleClass e1 = easyRandom.nextObject(ExampleClass.class);
ExampleClass e2 = new ExampleClass(Optional.of("asd"), Optional.of("asd"));

System.out.println(e1);
// note that printed fields are Optional[Object]
ExampleClass(a=Optional[java.lang.Object@7675f6], b=Optional[java.lang.Object@3117145]) 

System.out.println(e2);
ExampleClass(a=Optional[asd], b=Optional[asd])

e2.getA().ifPresent(System.out::println);
// Prints the fields value successfully if A is Some
e1.getA().ifPresent(System.out::println);
class java.lang.Object cannot be cast to class java.lang.String (java.lang.Object and java.lang.String are in module java.base of loader 'bootstrap')

Is there a fix planned for this issue?

This should be fixed now. I would be grateful if you can give it a try in 4.3.0-SNAPSHOT and share your feedback.
