    Don't drop relays with identical nicknames
    
    When our sybil checker sends notifications it sorts the relays by their
    nickname. To do this I constructed a 'nickname => descriptor' hash, but I
    forgot nicknames are not always unique. Actually, they very frequently aren't
    due to Unnamed entries.
    
    Constructing a 'nickname => [list of descriptors]' hash instead. Caught by
    Linus when yatei had an outage since we claimed 60 new relays but only listed
    34.
