Mortus Poisoners’ Dedicated Transport is requiring a Bolter equivalent

[m1rado]

Describe the bug
A clear and concise description of what the bug is.

Mortus Poisoners require one weapon choice per model, either Bolter or Alchem Flamer. Adding a Dedicated Transport increments the model count and then error checking seems to count that as a model which requires a choice of either Bolter or Alchem Flamer

To Reproduce
Steps to reproduce the behavior:

1. Go to add Mortus poisoners
2. Add Terrax termite drill
3. Only select 10 bolters for 10 models
4. See error

Expected behavior
A clear and concise description of what you expected to happen.

Only the models in the unit should require this choice
