For SQLState: 23506 h2 returns:
```
Referential integrity constraint violation: "FK_PROGRESS_CARD: PUBLIC.PROGRESS FOREIGN KEY(CARD_ID) REFERENCES PUBLIC.CARDS(ID) (0)"; SQL statement:
insert into progress (due, factor, card_id, user_id) values (?, ?, ?, ?) [23506-200]
```

H2Dialect's ViolatedConstraintNameExtracter currently only strips away everything up to and including `violation: `, making `constraintViolationException.getConstraintName()` return `"FK_PROGRESS_CARD: PUBLIC.PROGRESS FOREIGN KEY(CARD_ID) REFERENCES PUBLIC.CARDS(ID) (0)"; SQL statement:
insert into progress (due, factor, card_id, user_id) values (?, ?, ?, ?) [23506-200]`, which is obviously wrong.
