In Multirepository setup Workflows always use a default Database connection, so records may be placed in the wrong database.

Steps to reproduce
1. Clean installation of eZ Platform 2.5.6
2. Multirepository setup with two Databases: db-1 and db-2.
3. Two backends Siteaccesses admin and admin2, using different cache.pool and repository. admin uses default repository (db1), admin2 uses second repository (db2).
4. Set up Workflows like in the documentation example.
5. In admin2 backoffice, create Article and and send it to "Technical Review" with "Test" message.
6. Execute:

SELECT * FROM `ezeditorialworkflow_transitions`

on db2.

Result
There will be no record returned, as it was stored in db-1.

Expected Result
There will be a single record returned for previously created transition with the "Test" message.
