changed: - block range calculation no longer uses timestamps; it was prone to error if many slots were empty; now we get the blocks by querying SessionCommitteeManagement storage which consists epoch number - `test_block_authors_match_committee_seats` is asserting whole list of authors instead of just one existence of committee in proper order Refs: ETCM-9563
