      When overwriting a HABTM relation twice with the same value, the inverse foreign key ends up being empty:

      class A
  include Mongoid::Document
  has_and_belongs_to_many :bs, inverse_of: :as
end

class B
  include Mongoid::Document
  has_and_belongs_to_many :as, inverse_of: :bs
end

a = A.create
b = B.create

a.bs = [b]
puts a.reload.b_ids.inspect # => [id]
puts b.reload.a_ids.inspect # => [id]

a.bs = [b]
puts a.reload.b_ids.inspect # => [id]
puts b.reload.a_ids.inspect # => []

      Please see attached pull request for a corresponding failing spec. The commit also applies cleanly to master and the spec fails there as well.
