Subject: [PATCH] allow inserts with primary key nulled to be rolled back

when the row to be inserted contains `null` for its primary key column, it's most likely, that it's an auto-increment or otherwise generated primary key, so the row value is not reliable.

in that particular case, prefer the last insert id over the row value
