    Issues with router_get_by_nickname()
    
    https://trac.torproject.org/projects/tor/ticket/1859
    
    Use router_get_by_digest() instead of router_get_by_hexdigest()
    in circuit_discard_optional_exit_enclaves() and
    rend_client_get_random_intro(), per Nick's comments.
    
    Using router_get_by_digest() in rend_client_get_random_intro() will
    break hidden services published by Tor versions pre 0.1.2.18 and
    0.2.07-alpha as they only publish by nickname. This is acceptable
    however as these versions only publish to authority tor26 and
    don't work for versions in the 0.2.2.x series anyway.
