Reset crosshair on resets to fix spectator non-matching-to-player xhair (#1877)

This is kind of a guesswork if it'll fix the spectator seeing crosshair
on player that it's not the player's actual crosshair, but I'm assuming
the state haven't been refreshed properly especialy the timer till next
crosshair refresh and maybe on map change and where player index
changes it gets stuck with other player's crosshair.

* fixes #1735
