ui_1 - fix form_field_changed url to actually be the whole path, not just method name

If you acccess My settings via the menu, you end up at `/configuration/index`, so, POSTing observe events to `form_field_changed` actually works just fine.

But you can also end up at `/configuration`, which results in `/form_field_changed` for the POST.

Fixing to call `url_for` to get the full path
