Below is explenation, how it was possible to call it twice:

[pk_engine_finished_cb] pk-engine.c:554 (21:57:23):      backend was
running for 74 ms
[pk_transaction_db_sql_statement] pk-transaction-db.c:186 (21:57:23):
statement=UPDATE transactions SET succeeded = 1, duration = 74 WHERE
transaction_id = '3;cddcbaab;data'
[pk_engine_finished_cb] pk-engine.c:566 (21:57:23):      emitting
finished transaction:3;cddcbaab;data, 'success', 74

> first
