Fix web components which rely on API version

[fgravin]

Angular Services should never call a gn4API function on Service initialization, because for web component, the API_URL is not defined yet.

One should use cold Observable instead, to be sure that the API is fetched only if subscribed.

This fixes the Web components runtime.

Ok, I understand; the HTTP calls are already cold observables, but since the functions are called right away they use the API url before initialization. Thanks for the simple fix!
