To properly destruct an EnchantDict, its session field must be non-null since the destructor assumes a session has been associated with the object. This association happens in EnchantBroker when a provider upon request finds a valid dictionary and in doing so creates an EnchantDict object which is returned to the broker. In the AppleSpell provider, the EnchantDict was created regardless of whether the provider would be able to find a valid dictionary or not. If it did not find a valid dictionary, it would erroneously free the EnchantDict object and return null, despite the leaving the EnchantDict in the broker's set of dictionaries. This commit fixes the issue by moving the creation of the EnchantDict to occur after successfully finding a valid dictionary. Fixes rrthomas#391
