Don't call after_commit callbacks despite a record isn't saved

Regardless of a record isn't saved (e.g. validation is failed),
`after_commit` / `after_rollback` callbacks are invoked for now.

To fix the issue, this adds a record to the current transaction only
when a record is actually saved.

Fixes #29747.
Closes #29833.
