Inconsistent behavior when history_receiver.recv() returns None

[progval]

ServicesServer ignores it:

sable/sable_services/src/server/mod.rs

Lines 109 to 121 in 3c6bc2f

	update = history_receiver.recv() =>
	{
	if let Some(update) = update
	{
	if let NetworkStateChange::NewServer(new_server) = &update.change
	{
	if new_server.server == self.node.id()
	{
	self.burst_to_network().await;
	}
	}
	}
	}

but HistoryServer breaks the loop:

sable/sable_history/src/server/mod.rs

Lines 68 to 75 in 3c6bc2f

	update = history_receiver.recv() =>
	{
	let Some(update) = update else { break; };
	if let Err(error) = self.handle_history_update(update).await {
	tracing::error!(?error, "Error return handling history update");
	}
	}

HistoryServer is probably the correct one here, it looks like ServicesServer would enter an infinite loop when the associated sender is dropped
