Make it compatible to Sequel 5

Devise 4.3.0 confirmable module uses hooks like

    after_commit :send_on_create_confirmation_instructions, on: :create, if: :send_confirmation_notification?
    after_commit :send_reconfirmation_instructions, on: :update, if: :reconfirmation_required?

which invoke this deprecation warning of Sequel:

    SEQUEL DEPRECATION WARNING: Sequel::Model.after_commit in the hook_class_methods plugin is deprecated and will be removed in Sequel 5.  Use after_save{db.after_commit{}} instead.

This uses the recommended code for after_commit and allows to use the :on option.
