Continuations: Result does not contain all rows for BITMAP

[ohadzeliger]

When adding continuations to BITMAP query, the result only contain some rows.

Steps To Reproduce:

1. Look at bitmap-aggregate-index.yamsql

2. Change the test to run under Force Continuations

3. The test below only return the first row:

   • query: This
   • explain: "ISCAN(AGG_INDEX_1 <,>) | MAP (_ AS 0) | AGG (bitmap_construct_agg_l((._0.ID) bitmap_bit_position 10000) AS 0) GROUP BY ((._0.ID) bitmap_bucket_offset 10000 AS 0) | MAP (._1._0 AS BITMAP, _._0._0 AS OFFSET)"
   • unorderedResult: [{BITMAP: xStartsWith_1250'060000c', 'OFFSET':0}, {BITMAP: xStartsWith_1250'02', 'OFFSET':10000}]

Note: because of the unordered results it is harder to reproduce with adding maxRows. Potentially nullifying the result verification and adding maxRows: 1 can allow the test to first retrieve all results…
