Title: Fix attr_accessible handling

Closure Tree now works for me on Rails4 with attr_accessible

The class_eval used for building the new hierarchy class was not working as intended.

The accessible_attributes.present? check always returns false when building the new hierarchy class since the whitelist is always empty.
