Array inputs on event dispatcher cause a compiler note.

Looks related to [Link Removed], but it appears that something was overlooked. Probably requires a similar fix for the delegate node.

1. Create a new Blueprint class.
2. Add an event dispatcher with an Array input of type 'Actor Reference'.
3. Drag the event dispatcher into the event graph and choose "Assign."
4. Wire the exec pin on the "Bind" node to the exec pin on the "Event BeginPlay" node.
5. Compile. Note there is a compiler Note on the "Bind" node.

Expected result: No compiler note.
