    Views now retain update_seq after compaction.
    
    Previously on view compaction, the new index state would not carry
    over the associated database update and purge sequences. As a
    result, views who were compacted at least once could no longer
    use the ?update_seq query option, or purge properly.
    
    Closes #984
