test: update start_daemon_services test to target renamed helper after rebase

The rebase onto post-#276 main removed src/orb/interface/serve_command_handler.py
and moved the daemon-services init call into
server_command_handlers._initialize_application. Redirect the test at the new
target and drop unused sys/types imports.
