Fix sync tests after Syncing status introduction

- Fix relay_connected() helper to check v >= 2 (Syncing/Connected states)
- Fix unit test to use status value 3 (Connected) instead of 1 (Connecting)
- Fix clippy warning: use .to_vec() instead of .iter().cloned().collect()

All 61 sync integration tests now passing.
All 238 unit tests passing.
Clippy clean.
