ITEMS2.X: Fix import sometimes not properly triggering an actor sheet reload

[whitespine]

Issue:

Reproduce:

• Import a pilot by cloud code
• Clear gear from loadout
• Import again

The gear will still be deleted. Even worse, closing the sheet seems to sometimes save this invalid state. Pretty wacky!

I'm not overly concerned about the loadout issue - more concerned about what other side effects this might be having.....

Assigned myself, not claiming exclusivity but... Issue appears to be that:

• We call update. It properly shows in the console as having been called, with the expected diff to loadout
• The sheet refreshes.... but in the hook call it is using the pre-update data (?!??!?! what da hek)
• The sheet displays old data. However, accessing game.actors.get(whatever).data, and we see the correct data.
• Closing the sheet will immediately nuke this data. Only way to not clobber is to close the tab 🤦

This seems tied into general problems in curr. foundry version with race conditions on update -> render

We're waiting on 2.X for this. It mostly only becomes a problem if you're trying to make it a problem, honestly.
