Inconsistent results with `id` command on an ex-member
When asking for old members, the results of `id` command are not consistent :
```bash
$ silkaj -gt id elois
Public keys found matching 'elois':
→ D7CYHJXjaH4j7zRdWngUbsURPnSnjsCYtvo6f8dvW3C
$ silkaj -gt id D7CYHJXjaH4j7zRdWngUbsURPnSnjsCYtvo6f8dvW3C
No matching identity
```
The cause is :
When we have a pubkey, silkaj uses the path wot/identity-of/, that returns "not a member".
When we have a uid, silkaj uses the path wot/lookup/, that returns a result for old members also.
