Spring Data 2.0 uses Optional<T> findOne

[marceloverdijk]

The EntityGraphQuerydslPredicateExecutor currently uses the following signature:

T findOne(Predicate predicate, EntityGraph entityGraph);

In Spring Data 2.0 the {{QuerydslPredicateExecutor}} is changed to:

Optional<T> findOne(Predicate var1);

I think this library should upgrade to the Optional<T> as well for findOne.

Note EntityGraphJpaSpecificationExecutor already does this but EntityGraphQuerydslPredicateExecutor not yet.
