EntityClass cannot be used as expected

**UE4 Version**
All

**SkookumScript Version**
All

**Describe the bug**
The usage of `EntityClass` for `&blueprint` annotated functions is inconsistent. It should accept other variables of type EntityClass.

**To Reproduce**
Steps to reproduce the behavior:
1. Create a bp annotated function that takes an `EntityClass`
2. Create a variable of type EntityClass and note that you cannot pass it to the function

**Additional context**
Looks like there may be a missing link here, the reflection of class references to sk have no type information, so an class reference of type Pawn and a class reference of type GameMode both come in as `EntityClass`.
