    Make sure the microdesc cache is loaded before setting a v3 md consensus
    
    Otherwise, we can wind up munging our reference counts if we set it in
    the middle of loading the nodes.  This happens because
    nodelist_set_consensus() and microdesc_reload_cache() are both in the
    business of adjusting microdescriptors' references.
