fix: expo infinite loop on SAVEPOINT (#8984)
fix: expo infinite loop on SAVEPOINT (#8984)

some issues to use typeorm on expo :
- infinite loop on query method
- even if this infinite loop is fixed, db is stuck after SAVE POINT
- no id is returned on creation

with this fix, the expo-example can be updated successfully on typeorm 3 (with new DataSource api)
