Title: [ticket/11219] Update sequence values after loading fixtures

If a value is provided for an auto_increment type of column, certain DBMSes do not update their internal sequencers. If a row is inserted later, it can be given an ID that is already in use, resulting in an error. The database test cases now resynchronise the sequencers before the tests are run.
