Pressing use while holding bundles attempts to throw out items, even if it is empty.

Pressing the use key (or right-click for most players) while holding a bundle causes items to drop on the ground; However, if there are no items stored inside the bundle, the bundle still tries to drop its content on the ground anyways.

This means that the bundle will slow you down if you try to hold the +use+ button while holding it. This should be fixed because it is inconsistent with other +use+ mechanics.

Steps to reproduce

1. Give yourself a bundle. You can do this by running this command:

   /give @s minecraft:bundle

1. Hold right-click (or whatever is bound to the +use+ key).

Observed behavior

The bundle attempts to throw items no matter what, and also slows you down while doing so.

Expected result

The bundle would first check whether there are any items inside it and then try to throw them out and/or slow you down.
