Title: Return true even though the variables value is self::NULL.

We want this to be true:
$first = empty($entity->var);
$entity-var;
$first === empty($entity->var);

Which it wouldn't be before this change, if there was a getVar() method.

Of course, this could also be fixed by searching for a getVar() method as __get() does....
