      Spawner blocks and minecarts will unsuccessfully attempt to summon hostile entities when the world difficulty is set to peaceful

      Steps to Reproduce:

      1. Place down/summon one of the following: 
        /summon spawner_minecart ~ ~ ~ {SpawnData:{entity:{id:"minecraft:slime"}},SpawnPotentials:[{weight:1,data:{entity:{id:"minecraft:slime"}}}]}
        /give @p spawner{BlockEntityTag:{SpawnData:{entity:{id:"minecraft:slime"}},SpawnPotentials:[{weight:1,data:{entity:{id:"minecraft:slime"}}}]}} 1

      Expected & Observed Results:

      - The spawner will display cloud particles and a slime will appear for a brief moment, then despawn.
      - The spawner would not try and summon entities, as it cannot.
