Courier sync reported as failed even if successful

[gnarea]

The following is displayed at the end of every sync, even if the sync actually succeeded.

I narrowed down the issue to this line no longer having any effect, probably after upgrading the third-party lib ws:

awala-gateway-desktop/packages/daemon/src/server/control/courierSync.ts

Line 49 in 184f775

socket.close(1000);

The client is getting a 1005 code, which it doesn't expect:

awala-gateway-desktop/packages/ui/src/ipc/courierSync.ts

Lines 69 to 71 in a03b034

	if (closeEventCode !== 1000) {
	throw new CourierSyncError(`Socket error: ${closeEventCode}`);
	}

WireShark shows that the server is closing the connection without a close code, so it makes sense that the client gets a 1005.

I should try to upgrade ws-mock first as that could shed some light: #1110
