Able to select no hero in sandbox

[gibnewitems]

1. go into sandbox
2. click switch team in sandbox menu
3. press esc instead of picking a hero
4. congrats you're now playing a hero with no abilities

unable to buy items, move, or level abilities while in this state. trying to buy an active or imbue crashes the game. spawning a bot and then taking control through the sandbox menu causes it to show up at [bot] unknown in the team hud.
