[V22.5 Ground Combat] Alien turn doesn't end immediately when last xenonaut dies

Hi,

when your last xenonaut dies, the alien turn still continues, which can be quite long in some circumstances. It should end immediately as it does when you kill the last alien. Not sure if this should be a bug report or a feature request.

In general I think it would be a good idea to allow to open the main menu when it's the aliens turn, so you can quit or abandon the mission if something goes horribly wrong and you don't want to wait until the end of their turn.

It's on the work tracker so should be resolved sooner or later
