Usually hoppers aren't near items so we can avoid this lookup. Also avoid looking for minecarts if there are none, which there usually aren't These two lookups are the biggest cause of hopper lag, and these should help signifigantly.

Big thanks to @CullanP for suggesting this and providing me the initial patch.
This patch is a very simple and very effective patch, that @CullanP claims has large improvements (even before avoiding the minecarts).
I've tested, formatted and double-checked this PR.
