Minor bug in scenario without ssh tunnel

[zlochina]

The problem is that config variable always has attribute server, which means that db_server_port is always overwritten. I've encountered this issue when running pytest in main branch.
Suggestion:

• replace line 61 with if hasattr(config, "server") and config.server is not None:

road-graph-tool/python/scripts/process_osm.py

Lines 59 to 66 in b783c98

	def setup_ssh_tunnel(config: CredentialsConfig) -> int:
	"""Set up SSH tunnel if needed and returns port number."""
	if hasattr(config, "server"): # remote connection
	db.start_or_restart_ssh_connection_if_needed()
	config.db_server_port = db.ssh_tunnel_local_port
	return db.ssh_tunnel_local_port
	# local connection
	return config.db_server_port

Thanks for the suggestion, I'll add the second condition though the fact that the config always has server attribute depends on how the config is actually setup. Some might not need ssh connections at all so ssh is commented out/deleted completely - the original code worked with this scenario.
