Make sure new market slaves have correct pronouns

Run generatePronouns() after modifying slave parameters in the
GenerateMarketSlave widget. Otherwise when, for example, TFS school
creates a slave and then adds a vagina, the pronoum set in
GenerateNewSlave() before addind the vagina becomes obsolete.
