#385: Refactor id/lookup command using exclusively /wot/lookup

• Display non-member uids when passing a pubkey
• Use same algorithm as choose_identity() uses
  • Will display multiple time the pubkey and the differents uids if there is multiple uids linked to this pubkey
• 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 command to lookup:
  • Makes more sense and the identity cmd is about to be created

Will be cherry-pick to 0.9 branch and released if v0.9.0 in no additional rc is required.

Close #385 (closed).
