Crashes when reverting a model linked to not existing child model

Related: paper-trail-gem/paper_trail#841

How to reproduce:

1. I have Stadium and StadiumUser models, and the dependency between them is like that:

class StadiumUser < User
    ....
    has_one :stadium, foreign_key: "user_id", dependent: :destroy, required: true
    after_create :make_stadium
end

2. I created the StadiumUser (Stadium is created with it)
3. I deleted StadiumUser via rails_admin
4. I find the Stadium deletion entry and press "Restore"
5. this error appears

PG::ForeignKeyViolation at /stadium/history
ERROR:  insert or update on table "stadiums" violates foreign key constraint "fk_rails_b1bd5d1cc5"
DETAIL:  Key (user_id)=(56) is not present in table "users".

I can't check it for now, but it shouldn't work either, since no has_one: true param is specified when using paper_trail's reify.
Anyway, will check it out later.
