[web] Promisify MetricsEmailController and InstitutionHubsController (attempt 2) (#18805)

* Reapply "[web] Promisify MetricsEmailController and InstitutionHubsController …"

This reverts commit ea14df1395f1dc2fa7d41fc7837849f9686425b5.

* Fix changes to node-fetch: `statusCode` -> `status` (!!)

* Update test

* Handle no-content without throwing (!)

Avoid error `Unexpected end of JSON input` when doing `response.json()` on an empty response when status is 204

Related: https://github.com/node-fetch/node-fetch/issues/165

* Also return `204` when no data in departments_data and roles_data

* Revert "Handle no-content without throwing (!)", and return null instead

This reverts commits 3baa779f7a9e64804e54a276faf865ab9252f336 and 51507a3d763d7006c8b01414a7c79bd3f3b6948b.

* Update tests: `assert_nil`

* Fixup: Update tests: assert null

* Use `fetchJSON` in Institution.fetchV1Data

* Proxy errors from server without throwing 500
