Use createRemoteJWKSet for ID token validation

[pavol-brunclik-compote]

This PR fixes bug: Where when validating ID token against public key from JWKS store at index [0]. In case another private key was used to sign ID token, validation failed. Reintroduced usage of createRemoteJWKSet for ID token validation + fixed tests using 'nock' library mocking requests to JWKS endpoint.
