Fix carrying out soldier multiple times (#557)

The problem was that the game was setting the `bBodyRecovered` flag to true
and then never clearing it again. So you could carry a soldier out once, but
never again on any future missions.

This fix simply clears the flag at the beginning of tactical play.
