Lingering Potions lose their effect when thrown in survival

Throwing a lingering potion in survival mode will make the potion lose its effect (Doesn't affect creative mode).

[Client thread/ERROR]: ThrownPotion entity # has no item?!

This only occurs when the lingering potion is in a stack of one (similar to MC-105982 & MC-106043). If you have 2 lingering potions in 1 stack and throw it, it will work fine.
