Issues with aircraft husks killing units

[abcdefg30]

Since #14804 we always spawn husks from aircraft with an neutral owner. This seems to come with at least two issues when said husk hits the ground and the units at that location:

• Bounties are not awarded to the player
• Statistics are not updated correctly

One solution might be to only spawn husks with a neutral owner when the player dies at the same time. Husks already created when a player gets defeated will then be destroyed immediately though (#14804 (comment)).
