FIX: correctly render html of event title

[jjaffeux]

This has been lost during the move to glimmer.

We need to escape topic.title as well.

If we want to keep this all manual, then I think we should split it up like:

Suggested change

	return htmlSafe(
	emojiUnescape(
	escapeExpression(this.args.event.name) ||
	this.args.event.post.topic.title
	)
	);
	const unsafeRawTitle = this.args.event.name || this.args.event.post.topic.title;
	const escapedTitle = escapeExpression(unsafeRawTitle);
	const escapedTitleWithEmoji = emojiUnescape(escapedTitle);
	return htmlSafe(escapedTitleWithEmoji);

---

Or, even better, we can do the emoji escaping using our hbs helper which has all the escaping built-in.

So make the getter a simple thing like:

get eventName(){
  return this.args.event.name || this.args.event.post.topic.title;
}

and then import/use the helper:
...

import replaceEmoji from "discourse/helpers/replace-emoji";
...
<template>
  {{replaceEmoji this.eventName}}
</template>
