[Bug]: Internal types printed to chat when exporting a library token as an add-on

[kwvanderlinde]

Describe the Bug

After right-clicking a Lib:token and selecting Export Library Token as Addon... and choosing a folder, a completion message is printed to chat to indicate that the export was successful. This intent appears to be for the message to include the name of the exported library, or possibly the Lib:token it was generated from, but instead includes a string along the lines of java.util.concurrent.CompletableFuture@5667d59b[Completed normally].

To Reproduce

1. Add a token to a map.
2. Rename the token to Lib:token
3. Right-click the token, choose Export Library Token as Addon..., pick a folder, and click Save.
4. Look in chat. You should see the following message:

   Exported java.util.concurrent.CompletableFuture@5667d59b[Completed normally] to … as add-on library. Its likely you will need to make modifications to the add on library to make it work.
   

Expected Behaviour

The message should include the name of the Lib:token or the name of the exported add-on. There should be no Java types included in the message.
