In order to repdoruce potential bug with oneToMany/oneToOne in ORM

1. comment out all init_* functions but not init_teams().
2. run it ( v -d trace_orm run fixtures.v ) teams table will be created and populated with data.
3. comment out all init_* functions but not init_predictions_no_orm()
4. run it again. predictions table will be created and populated with data
5. now, comment everything but not init_predictions_simplified() and run it -> script panics with "V panic: db.sqlite.SQLError: UNIQUE constraint failed:" while trying to insert into teams instead of inserting into predictions table
