      Since commit 5a1f8f3b5256af3cfb3d3fc99737c37a3660591e (RE: MONGOID-2943), binding of a referenced-in relation no longer works right, because the inverse relation is set to the document itself rather than a relation proxy wrapping it:

      class Parent
  include Mongoid::Document

  has_one :child, inverse_of: :parent
end

class Child
  include Mongoid::Document

  belongs_to :parent, inverse_of: :child
end

parent = Parent.new
child = Child.new

child.parent = parent

parent.child = nil # or parent.child = Child.new — same thing happens
# => NoMethodError: undefined method `substitute' for #<Child:0x007f92b6a52be8>

      I've reverted the commit in my own fork, but obviously that's not a good solution as it returns the extra query on has_one relations.
