items don't go back into off-hand

[Shadowdragon352]

• DeadChest 4.6.0
• Paper 1.17.1 209

if a player has a full inventory and something is in their off-hand when they die and then recover their items the item that was in their off-hand gets dropped on the ground and not put back into their off-hand.

Steps to reproduce the behavior:

1. fill inventory and off-hand
2. die
3. recover items
4. item from off-hand gets dropped on the ground

Expected behavior
The item should be placed back into the players off-hand so it doesn't risk being lost or destroyed potentially by lava.

This is for me an enhancement of the auto-equip stuff feature more than a bug.
