(n ahead) after shuffling wrong

[njk345]

I noticed that after a queue gets shuffled, the "(n ahead)" message in the tab does not get updated and shows the number from before shuffling. This was at least true for Safari on Mac.

This is where the title is set:

signmeup/imports/ui/pages/queue/queue.js

Lines 76 to 92 in e366286

	const studentTicketIndex = queue
	.tickets()
	.fetch()
	.filter(t => t.status === "open")
	.findIndex(t => t.belongsToUser(Meteor.userId()));
	let prefix;
	if (studentTicketIndex === -1) {
	prefix = queue.activeTickets().count();
	} else if (studentTicketIndex === 0) {
	prefix = "you’re next";
	} else {
	prefix = `${studentTicketIndex} ahead`;
	}
	document.title = `(${prefix}) ${queue.course().name} · ${
	queue.name
	} · SignMeUp`;

Somehow, it must not get called after the queue is shuffled. It seems to get called for most other updates, so I’m not sure why this could be.
