Some API calls use a different endpoint

[avivace]

Me and @carmenmarcos00 noticed a quite strange bug while trying to deploy InvenioRDM on VM on a custom host:

• We started by installing InvenioRDM following the "local installation"
• We modified invenio.cfg as follows:

SITE_UI_URL = "https://<PUBLIC_IP>"
SITE_API_URL = "https://<PUBLIC_IP>/api"
APP_ALLOWED_HOSTS = [<PUBLIC_IP>, '0.0.0.0', 'localhost']

• InvenioRDM is started with

invenio-cli run --host 0.0.0.0

(this is actually wrong, but it's for the purpose of triggering the bug)

InvenioRDM is then accessible on https://<PUBLIC_IP> and every api call from the frontend seems to be working (so it seems to be using SITE_API_URL from invenio.cfg`)

However, some features (e.g. Publishing a Draft) trigger some API calls that are executed against 0.0.0.0 (so ignoring what we set in invenio.cfg), obviously failing with a generic errors (because the browser is not being executed from the VM itself), while the others are against <PUBLIC_IP>.

I'm sure this also involves the main codebase and not only the cli one, but needs more investigating.
