ExposeOnSpawn Class properties do not respect "none" as the value on "Construct object from class" node

I think that the root of the issue actually comes from the K2 node behavior itself. If you copy your node and paste it to a clipboard, you can see the pins and the string representation of all the values. When I set mine to "None", the pin is assuming the default value of the Expose on Spawn variable, instead of actually respecting "none" as the value you want. 

1. Create a Blueprint based on UObject
   1. Add a Object Class reference variable
   2. Mark this as "Expose on spawn" and "Instance editable"
   3. Compile/save
   4. Set the default value of this variable to anything
   5. Add a function called "Print class name" which prints the display name of this variable
2. In another blueprint, call "Construct object from class" and select this blueprint class type
3. Set the class variable to "None"
4. PIE

Result: The class name will be the default value you set in the blueprint, not "none" which you have specified on the node.

Expected: "None" is printed out by the Print Class Name function.
