portal: Expand allowed graphs to full URIs for notifier filtering

We get fully expanded graph names from TrackerNotifier events, but
we allow prefixed names in flatpak rules. Expand the latter so we
match both, as a last resort.

This fixes propagation of changes from these graphs to the sandboxed
applications.
