Title: Fixes validates with :uniqueness option

Moved `Ambry::Validations::Uniqueness` to `ActiveModel::Validations::UniquenessValidator` to support `validates :attr, :uniqueness => true` syntax apart from of `validates_uniqueness_of` (`ActiveModel#validates` looks for custom validations in `ActiveModel::Validations::#{CustomValidator}Validator`).
