Update EmptySliceBehavior.cs

Putting this back the way I found it (commented it out because I can't get standalone builds to run with it enabled, local issue)

Assets/BossRoom/Scripts/Shared/SliceBehaviors/EmptySliceBehavior.cs

-/*
-public class EmptySliceBehavior : SliceBehavior
-{
-    public override void OnAllSlicesStarted()
+    public class EmptySliceBehavior : SliceBehavior
-    }
+        public override void OnAllSlicesStarted()
+        {
+        }
-    public override void OnSliceMessageReceived(int senderId, string message)
-    {
+        public override void OnSliceMessageReceived(int senderId, string message)
+        {
+        }
+
