Subject: [PATCH] Fix rare crash in AI code

Reported in https://forums.wesnoth.org/viewtopic.php?p=626344#p626344

Regression from commit a3d5b9d603083ab0f3afcfbc9fc4c2432bb1623e.

The crash occurred when
* the attacker had only one weapon
* the said weapon was disabled, and
    - the defender had no weapons
    - the defender had only one weapon, or
    - all defender's weapons were disabled

(cherry-picked from commit 4d569815d00fc0bb7be9fcc83705ebbf9a680bd8)
