Update js-cookie node module to 3.0

There is a new upstream version of js-cookie node module. Please update the version used in gitlab.

This release has a breaking change as documented here, https://github.com/js-cookie/js-cookie/releases/tag/v3.0.0

Removed defaults in favor of a builder: now to supply an api instance with particular predefined (cookie) attributes there's Cookies.withAttributes(), e.g.:

const api = Cookies.withAttributes({
  path: '/',
  secure: true
})
api.set('key', 'value') // writes cookie with path: '/' and secure: true...

We would like to update js-cookie 3.0 in Debian and this update will help in that transition.
