[MC-91050] Armor stands can have potion effects

Fix note

ArmorStands can still have potion effects, however potion affects from thrown splash potions or lingering potions are not applied to them (see [Mojang] Searge (Michael Stoyke)'s comment).

The bug

ArmorStands can have potions but they do not affect them and they also show no particles.

How to reproduce

Place an armor stand
Throw a splash or lingering potion at the armor stand
Inspect the NBT data of the armor stand (for example by using the /entitydata command)

You will probably find the ActiveEffects tag

Note: This also causes them to consum lingering potions
