Extraneous certifier logging

[jacogr]

Dev console fills up with warning logs -

Error: Certifier 0 does not exist.
(anonymous) @ middleware.js:183
middleware.js:183 Error: Certifier 1 does not exist.
(anonymous) @ middleware.js:183
middleware.js:183 Error: Certifier 2 does not exist.
(anonymous) @ middleware.js:183
middleware.js:183 Error: Certifier 3 does not exist.
(anonymous) @ middleware.js:183
middleware.js:183 Error: Certifier 4 does not exist.
(anonymous) @ middleware.js:183
middleware.js:183 Error: Certifier 6 does not exist.
(anonymous) @ middleware.js:183
middleware.js:183 Error: Certifier 7 does not exist.
(anonymous) @ middleware.js:183
middleware.js:183 Error: Certifier 10 does not exist.
(anonymous) @ middleware.js:183
middleware.js:183 Error: Certifier 11 does not exist.

from

.catch((err) => {
                  if (/does not exist/.test(err.toString())) {
                    return console.warn(err.toString());
                  }

                  console.warn(`Could not fetch certifier ${id}:`, err);
                });

Probably best to squash these "does not exist" errors, the normal error logged afterwards is a worth-while concern.
