    Add database defaults for new fields provider_id and settings in table socialapp.
    This field was added by 0004_app_provider_id_settings.

    The database default is used by our migrations tests. In practice, it is unlikely
    and unwise to add a new SocialApp in the middle of a deployment.

    `./manage.py sqlmigrate` did not work, so the sqlite3 steps are manual.
