[tor-commits] [onionoo/master] Always add own fingerprint to effective family.

commit a9a0f7054cf66ee51b245b02369119832e330585
Author: Karsten Loesing <karsten.loesing@xxxxxxx>

    Always add own fingerprint to effective family.
    
    Some relays include their own fingerprint in the family line of their
    server descriptor and others don't.  To provide consistent data Onionoo
    now adds a relay's own fingerprint to its effective family.
    
    Implements task-25241.
