Arrays of Soft Object local variables are not captured for reference graph

This bug comes from https://udn.unrealengine.com/questions/492861/view.html and is a very similar problem to [Link Removed]

The issue is that the code that harvests soft object references stored in local variables doesn't work with arrays/maps because it's doing a manual extract. The fix is to switch it so local variables are stored as proper UProperties inside the blueprint

1. Create a blueprint, add a function to it, add an Array of Soft Object Reference as a local variable
2. Add a reference to the array, point it an asset like a texture. Compile and save blueprint
3. Open reference viewer for that blueprint, the soft object reference will be missing. If it was a single reference it would work, or if the array was a class variable instead of a function local
