[Client] Champion Portrait after Teambuilder Closes

1. Have a friend create a new teambuilder lobby and invite you to it.
2. Enter the champion select screen, and hover over a champion you would like to play, revealing their portrait to your left.
3. Have your friend close the teambuilder lobby.

Expected Result: The portrait vanishes along with the rest of the teambuilder UI. Actual Result: The portrait remains on screen until the user returns to a teambuilder champion select screen to hover over a new champion.
