commit 07f2940b4519d801eb10b9f5e49790aced1f6322
Author: Alexander Færøy <ahf@xxxxxxx>
Date:   Fri Jun 23 23:55:54 2017 +0000

    Set published_out for consensus cache entries in spooled_resource_estimate_size().
    
    This patch ensures that the published_out output parameter is set to the
    current consensus cache entry's "valid after" field.
