donations_queue_consume-20180425-010701 sent out 32 failmails, all with the same pattern:
A donation from the audit file (NL iDEAL donations mostly all come in via audit) is inserted, but there are a couple of errors. First we see
```
WD wmf_civicrm: Error inserting contribution: contact_id is not valid: XXXXYYYY
```
Then we see this error:
```
Cannot add or update a child row: a foreign key constraint fails (`civicrm`.`wmf_contribution_extra`, CONSTRAINT `FK_wmf_contribution_extra_entity_id` FOREIGN KEY (`entity_id`) REFERENCES `civicrm_contribution` (`id`) ON DELETE CASCADE)]',
```
So somehow we're trying to insert the contribution, and it's failing because it can't find the contact, but we keep going and try to insert a wmf_contribution_extra row which fails 'cause it can't find the contribution.3696c652e
