PrepareResultEvent is fired twice within ItemCombinerMenu#slotsChanged #10865

Description

Expected behavior

I believe PrepareResultEvent only needs to be fired once per ItemCombinerMenu#slotsChanged method call.

This method calls this.createResult() which is implemented by SmithingMenu#createResult, which fires a PrepareResultEvent event, before being fired a second time immediately after within slotsChanged. It is of my assumption that the event call within SmithingMenu is not actually needed, or I'm misunderstanding why it is there.

Observed/Actual behavior

There are twice as many PrepareResultEvent events being emitted than what seems to be necessary resulting in a total of 6 calls when slotsChanged is only called 3 times.

Other

This is in regards to the "Add PrepareResultEvent" patch, seems to have been present for quite some time too. While a similar issue to #4844, I'm aware that the event is currently intended to fire multiple times, this issue is more about the duplicated calls that occur within the slotsChanged method alone.
