A bug discovered on my server. We're running vanilla software and are just using gametest scripts and command blocks to customize it. One of the protections we have in place is to kill all projectile entities at our spawn. This includes arrows, tridents, and fishing hooks. This has been flawless until recently; Fishing Hooks, when killed, instantly generate loot from the fishing loot table. 

Steps to reproduce
Load into any world
Create a command block with `kill @e[type=fishing_hook]`
Use a fishing rod to throw a fishing hook

Observed Results
Upon the "death" of the fishing hook entity, fishing items are spawned.

Expected results
The fishing hook just just vanish, like all thrown or shot entities

This goes against vanilla parity with Java, and also causes issues with servers or worlds that do not wish to allow players to use fishing rods in certain areas.
