Description

Wrong results for

• select count on marked for delete segment
• select count on compacted segment

Issue comes only when the user explicitly sets deleted/compacted segments using the property carbon.input.segments.
As select * on such segments gives 0 rows as output, in order to maintain consistency, select count should also give 0 rows.
