The event and that appearance will go away automatically soon (the event is slated to end on Nov. 11).

If you want to opt out earlier, you can go to the game's properties in Steam (either by right clicking the game in your Library list or using the little gear icon in the top corner of its Library page), go to the betas tab, and opt into the "testing" branch. This branch currently uses the regular version of House Party's latest version and gets auto-updated just like the default/"none" branch.
