Fix `collection.create` to could be rolled back by `after_save`

In `_create_record`, explicit `transaction` block requires rollback
handling manually when `insert_record` is failed.

We need to handle it in `_create_record`, not in `insert_record`, since
our test cases expect a record added to target and returned even if
`insert_record` is failed,

Closes #31488.
