Unless the user signed up after changes from Github issue #2057, the contact list delegate would never be set due to a logic error, which means latest_contact_event_changed would never get called and the app would never save a local contact list reference to pull from — which caused issues when switching to different relays.
Testing
--------
PASS
Device: iPhone 15 simulator
iOS: 17.5
Setup: Manually removed UserSettingsStore::latest_contact_event_id_hex value to replicate the entry condition for the bug
Steps:
1. Add new relay (relay.zap.store)
2. Remove all other relays
3. Attempt to add relay. Ensure new relay can be added
4. Remove all relays
5. Add the `wss://notify-staging.damus.io` relay (which will not save any events)
6. Restart app
7. Try to add a new relay. Ensure a new relay can be added
8. Make a test post. Ensure the new test post is posted successfully.
Changelog-Fixed: Fixed some scenarios where the contact list would never be saved locally and cause issues when switching relays.
