Make tutorial lines update the player position more times per second (to reduce jitter)

To ensure less jittery experience. This jitter is now pretty visible due to: #5087

Should be doable by refreshing the line data even when there is no new target to update the line to be from the player cell (or if that is already done then swapping the line update after the gameplay update should make them match up better).
