Fix missing null character check on guest_access room state
When updating room_stats_state, we try to check for null bytes slipping in to the content for state events. It turns out we had added guest_access as a field to room_stats_state without including it in the null byte check. Lo and behold, a null byte in a m.room.guest_access event then breaks room_stats_state updates. This PR adds the check for guest_access. A further PR will improve this function so that this hopefully does not happen again in future.
