[1.3.3074, Ideology] Aerial Assault Quest requires more colonists than sendable

[fsturnip]

Quests are generated which need more pawns than sendable, see screenshot: 20 colonists + 6 slaves

Quest generated requires 21 colonists

However, slaves do not qualify to send on shuttle.

Not sure if intended, but seems like it could be a bug where slaves havent been excluded from the requirements calculation.

Thanks for the bug report, I was able to reproduce this issue.  I'll advise the devs!
