      Using: 4.0.0.beta1

      Given:

      class School
  include Mongoid::Document
  
  has_many :students
end

class Student
  include Mongoid::Document

  belongs_to :school

  scope :enrolled, -> { where(state: 'enrolled') }
end

school = School.new
student = school.students.build()
student.school == school # => true

      Then if I use a scope, say enrolled, I might expect similar behavior, except I get: 

      school = School.new
student = school.students.enrolled.build()
student.school == school # => false
student.school.nil? # => true
student.state # => "enrolled", expected behavior for this scope

      So the parent of the relation doesn't stay attached to the new child when using a scope.
