Minor restatectl improvements

This fixes the logs list view and shows the configuration in a proper way

Log Configuration (v3)
Default Provider Config:
 └ Logs Provider: replicated
   ├ Log replication: {node: 2}
   └ Nodeset size: 0
 L-ID  FROM-LSN  KIND        LOGLET-ID  REPLICATION  SEQUENCER  NODESET
 0     2         Replicated  0_1        {node: 2}    N1:2       [N1, N2, N3]
 1     1         Replicated  1_1        {node: 2}    N3:1       [N1, N2, N3]
 2     2         Replicated  2_1        {node: 2}    N1:2       [N1, N2, N3]
 3     1         Replicated  3_1        {node: 2}    N3:1       [N1, N2, N3]

instead of

Log Configuration (v3)
Default Provider Config: Replicated(ReplicatedLogletConfig { replication_property: {node: 2}, target_nodeset_size: NodeSetSize(0) })
 L-ID  FROM-LSN  KIND        LOGLET-ID  REPLICATION  SEQUENCER  NODESET
 0     2         Replicated  0_1        {node: 2}    N1:2       [N1, N2, N3]
 1     1         Replicated  1_1        {node: 2}    N3:1       [N1, N2, N3]
 2     2         Replicated  2_1        {node: 2}    N1:2       [N1, N2, N3]
 3     1         Replicated  3_1        {node: 2}    N3:1       [N1, N2, N3]
