    Do not treat empty key_name as None

    When running instance, empty ("") key_name is treated as None and
    keypair lookup does not happen. However, empty string is written to
    key_name field in instance's database record. When horizon renders
    instance info, it looks up keypair if key_name is not None. Having
    empty string in this property generates error and instance info is not
    displayed.
