Display non-member uids when passing a pubkey
Use same algorithm as choose_identity() uses
The uids were already in /wot/lookup/
Remove identity_of() call which can only get member uids
Rename `pubkey(s)` to `lookup(s)`
When passing a uid, use /wot/lookup/ instead of
identity_of() which only gets member uids
Rename variable, rename command description
Use f-string, use one click.echo() call
Rename `id` to `lookup` command:
Makes more sense and the `identity` cmd is about to be created
