field of type Set is returing incorrect type (easy fix)

Hi,

Discovered this today inside: DefaultCreator.java

public <T> T createInstance(final Class<T> clazz) {
        try {
            return getNoArgsConstructor(clazz).newInstance();
        } catch (Exception e) {
            if (Collection.class.isAssignableFrom(clazz)) {
                return (T) createList(null);
            } else if (Map.class.isAssignableFrom(clazz)) {
                return (T) createMap(null);
            } else if (Set.class.isAssignableFrom(clazz)) {
                return (T) createSet(null);
            }
            throw new MappingException("No usable constructor for " + clazz.getName(), e);
        }
    }

Problem is that an Set class is also a collection. To solve it just flip the if statments like so:

if (Set.class.isAssignableFrom(clazz)) {
                return (T) createSet(null);
            } else if (Map.class.isAssignableFrom(clazz)) {
                return (T) createMap(null);
            } else if (Collection.class.isAssignableFrom(clazz)) {
                return (T) createList(null);
            }

I would create a PR but i have some issues with my repo... :(
