Update to Nock v14.0.0

[busma13]

Nock v14.0.0 made some breaking changes:

• Nock now uses @mswjs/interceptors for mocking. On 204 responses the body is no longer returned. This breaks any test that returns a 204 and a response body. We should make those responses 200s instead.
• replyWithError with object does not work since beta-8+ nock/nock#2789 and controller.errorWith ends up in the response path if the error is not Error instance mswjs/interceptors#625 track an issue related to replyWithErrors that needs to be fixed before we can upgrade.
