door xp in Face of the Enemy not applied

[Konrad22]

Very minor issue:
When tearing down the gate/door in the screenshot, your units are all moved into the room. The unit destroying the door does not gain the expected 4xp from the door.

Probably multiple cases of this throughout both campaigns, including bosses.

I'm not particularly interested in fixing this particular case, so patches welcome.
