Sometimes wouldn't restoring with recursive and recovery_window has_one model

[kinkinkon1009]

Hi.

In my application, I encountered unintentionally behavior.

With this simple example

class ParentModel < ApplicationRecord
  acts_as_paranoid
  has_one :child_model, dependent: :destroy
end

class ChildModel < ApplicationRecord
  acts_as_paranoid
  belongs_to :parent_model
end

There are related one ParentModel and two ChildModels records.
They are all deleted.

One ChildModel is deleted 20minutes ago.
One ParentModel and the other ChildModel is deleted 5minutes ago

And then call #restore with recursive and recovery_window.

parent_model.restore(:recursive => true, :recovery_window => 10.minutes)

ParentModel is restored intentionally.
But no ChildModel is restored.

I haven't worked this Issue and PR for a long time.
So once I closed it.
