World unload event not invoked when unloading persistent worlds

[LCLPYT]

How to replicate this issue

• register a listener on ServerWorldEvents.UNLOAD
• start test mod client or server
• /fantasy_open test:test
• /fantasy_unload test:test
• verify the listener wasn't called

The event is called however, when using /fantasy_delete test:test.

Comment

It appears that the "setDone" method of the ProgressListener in RuntimeWorldManager#unload is no longer called. Maybe the event should be invoked after the world removal as in delete?
