Fix modem URL not updating for credential-free drivers

The URL default was applied after the credentials_required check,
so modems like the Hitron CODA-56 would keep showing the FritzBox
default URL (192.168.178.1) instead of their own (192.168.100.1).

Move the URL update before the early return in both setup wizard
and settings page.

Fixes #175
