Fix team chooser menu popup when other player in PVS (#511)

* `C_NEO_Player::Spawn` is called not only for the local client's
  player, but also for other player (bot or actual) when they're in the
  local client's PVS
* If it's called, then only update the VGUIs if it's either local player
  wasn't set (so it's initially just spawned in) or matches the set local
  player's pointer.
* fixes #510
