Destroy HUDs once the timer runs out
The mapvote HUDs used to stay until the map rotated which as a result would display the mapvote HUDs even when the timer had run out and the game was trying to only display the scoreboard to have a clean post game screen.
It would also unnecessarily allow players to still use the menu although the vote was already ended
Change mapvote_limits_max from 11 to 10
After some testing there are a few maps that don't display all HUDs if we have 11 elements so it's safer as a default value
