Invalid Loot Table names containing periods (".") do not create error message

Relates to:

• MC-91061: Probably caused by the fix

The bug

When you provide a LootTable name with a period the game is unable to find a loot table but does not print an error indicating this.

How to reproduce

1. Use the following command

   /setblock ~ ~ ~ chest 0 replace {LootTable:"invalid"}
   

2. Open the chest
   → The error is printed in the log: "Couldn't find resource table minecraft:invalid"
3. Use the following command

   /setblock ~ ~ ~ chest 0 replace {LootTable:"invalid2."}
   

4. Open the chest
   → No error message is printed

The reason

The following is based on a decompiled version of Minecraft 1.9 using MCP 9.24 beta.

The reason for this is that the method net.minecraft.world.storage.loot.LootTableManager.Loader.load(ResourceLocation) only prints the error message

Invalid loot table name '[LOOT_TABLE]' (can\'t contain periods)

as debug message and not as error message.
