nixos/firefox-syncserver: fix setup failure due to duplicate key

Browse Source 
in some circumstances, the setup service would fail with:
ERROR 1062 (23000) at line 5: Duplicate entry '1' for key 'PRIMARY'
so let's use an upsert instead of insert. This also simplifies the
script.

Besides, also fix that when the setup script changes, the corresponding
script is not restarted as it is usually not active, so we trigger a
restart of the main systemd service.
