Implement more efficnet onConflictStrategy
When inserting objects to database tables it may not hurt the unique constraint of the primary key. At the moment all rows, which are already inserted are replaced by a new row with same data. This is very unefficent. Idea for solving this: add a checksum to every row. If an object with the id is already inserted, compute checksum of it. If the checksum is also identical -> do noting. Otherwise update the row bc some value of the object has changed.
