Fix the rotation of Minecarts and thrown entities.

Whenever I throw an item like a snowball, egg or ender pearl, it will face another direction than it is going. And the same is happening with Minecarts. I find this quite awkward for when I want to make a datapack that uses the direction they are traveling as I can't use the direction it is looking through ^ ^ ^ but I am forced to use motion or spawn another entity that will face the Minecart or thrown item from behind to find the direction heading. So if there was a change that made minecarts and thrown items face the direction they are heading, that would be so awesome.
