Don't use single-object arrays in queues + queue building fixes.

- There is no benefit in storing the result of each row in an array when the result only has one column. Store the values directly in the list for efficiency.
- Don't clear the list until we know we are actually replacing it with new data.
- Explain why we don't reverse the queues like in libanki.
