[Unstable build] Mental breaking pawns don't drop carried pawn

[cajk]

If a colonist is carrying or rescuing (and possibly arresting) another pawn but mental breaks while they're carrying them, they don't drop the carried pawn and just wander around holding them . I don't have a save file sorry but should be easy enough to recreate.

Thanks for the bug report. I was able to reproduce this in 1.4.3521 and made a report for the devs.
