Fix IncompatibleClassChangeError with allowClickingOwnInventoryIfClickingEmptySlotsIsPrevented

[nentify]

Workaround error by using setter instead of getter, seems to stop the error occurring

Can reproduce with the changing-title interface in the example plugin, the error no longer happens after applying this fix

The error occurring without this fix:

[20:54:49 INFO]: nentify issued server command: /interfaces changing-title
[20:54:50 ERROR]: Could not pass event InventoryClickEvent to ExamplePlugin v1.0.0
