Removing remnants of old functions after parser cleanup

Just a few places that relied on the old `pc.lowerGarments()` and `pc.upperGarments()` functions that were removed in 4c3bc2a2ac. Teasing using chest or crotch would not work before since the functions no longer exist, but this fixes it.

I searched for a similar function call and found that one in `includes/sellesy.as`. Didn't test that one specifically, but since it's a fairly straightforward change I'm pretty confident it'll fix that issue there as well.
