Spine events not being sent.

[JCash]

Gui: https://forum.defold.com/t/gui-spine-event-def-3056-solved/14810/6?u=mathias_westerdahl

2: If I put a spine model in a Gui object and let the default animation run. Then it will not send event messages.

Go: The spine_event aren't sent to the Lua callback.
