Resolution Note (fix version 0.14.0):
Fixed in: Entities 0.14.0 - preview.18
The root issue here is that `new EntityArchetype()` returns an invalid value that you're not supposed to use. To get valid EntityArchetype values, you must call `EntityManager.CreateArchetype()` instead.
We unfortunately can't stop you from instantiating invalid values because a struct's default constructor cannot be overridden or hidden.
So our fix is that safety checks in CreateEntity() and SetArchetype() will now throw an exception if you pass the invalid EntityArchetype value.
