Subject: [PATCH 2/7] Fix confusing error when failing to add an alias to an
 unknown account (#13480)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-up to #13452, fixing broken `uri.nil?` test.

Also remove the separate check for `uri` presence, as that would result
in a “Please review 2 errors below” while only one would be listed.
