The intention here is to make the required config copy-able from the console/logs, so add a newline at the end of the message to make that easier. (Otherwise it would be `... raise_in_transactional_callbacks = true (called from...`.)

Autosave callbacks shouldn't be `after_save` callbacks

068f092c registered autosave callbacks
as `after_save` callbacks. This caused the regression described in #17209.

Autosave callbacks should be registered as `after_update` and
`after_create` callbacks, just like before.

This is a partial revert of 068f092c.

Fixes #17209.
