Dependents are tracked incorrectly through sibling documents

      It seems that declaring dependents in one document type also adds these dependents to any sibling class. Attempting to delete or destroy an instance of the sibling therefore fails.

      Example:

      class ReportCard
  include Mongoid::Document
end

class User
  include Mongoid::Document
end

class Student < User
  has_many :report_cards, class_name: 'ReportCard', dependent: :destroy
end

class CollegeUser < User
end

def main
  c = CollegeUser.create
  puts c.dependents
  c.destroy
end

      The output of the above is as follows:

      #<Mongoid::Association::Referenced::HasMany:0x00007fdd5ad031a0>
NoMethodError: undefined method `report_cards' for #<CollegeUser2:0x00007fdd50872cd0>
from /Users/luke/.rbenv/versions/2.3.7/lib/ruby/gems/2.3.0/gems/mongoid-7.0.1/lib/mongoid/association/depending.rb:86:in `_dependent_destroy!'
