nixos/tests/centrifugo: fix shards address list order in tests

Redis shards list must be consistent between Centrifugo nodes. Before
this change, NixOS tests were using invalid configurtaion since
shards[hash(ch)] may select different Redis shard instance on each
Centrifugo node. We don’t currently have any tests that exposed this
behavior though.
