update oidc and silent-renew

[sei-jmattson]

Updated oidc dependency and fix silent-renew.

Recommended oidc settings:

oidc: {
  client_id: 'dev-code',
  authority: 'http://localhost:5000',
  redirect_uri: 'http://localhost:4200/oidc',
  silent_redirect_uri: 'http://localhost:4200/assets/oidc-silent.html',
  response_type: 'code',
  scope: 'openid profile dev-api',
  loadUserInfo: true,    // generally needed for our apps since we don't really use an id_token
  useLocalStorage: true, // true means auth_token is used browser-wide; false means each tab has to get a token
}
