Copying Gameplay Tag Queries uses paths of instanced objects.

Copying Gameplay Tag Queries (FGameplayTagQuery) in the editor uses transient instanced object paths, so will no longer be valid when the data is unloaded, making it difficult to save or share queries.

1. Start editing a Gameplay Tag Query
2. Create some expressions (like All Expressions Match, Any Tags Match)
3. Copy the expression
4. Paste it into a notepad
5. Observe that the object itself was copied, not its values
6. Click around in the editor for some time
7. Paste the expression to a query
8. Observe that 'None' is shown instead of the original hierarchy you've copied (if it's still valid, then play around in the editor some more until those objects are completely out of GC)
